Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540440, here are decompositions:

  • 3 + 540437 = 540440
  • 7 + 540433 = 540440
  • 67 + 540373 = 540440
  • 73 + 540367 = 540440
  • 97 + 540343 = 540440
  • 139 + 540301 = 540440
  • 157 + 540283 = 540440
  • 223 + 540217 = 540440

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 540,440 and was likely granted around 1894.

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

Position in π

The digit sequence 540440 first appears in π at position 955,219 of the decimal expansion (the 955,219ordinal-suffix:th 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.
