Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008440, here are decompositions:

  • 3 + 1008437 = 1008440
  • 7 + 1008433 = 1008440
  • 19 + 1008421 = 1008440
  • 31 + 1008409 = 1008440
  • 61 + 1008379 = 1008440
  • 67 + 1008373 = 1008440
  • 109 + 1008331 = 1008440
  • 193 + 1008247 = 1008440

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,008,440 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1008440 first appears in π at position 448,172 of the decimal expansion (the 448,172ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
