Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492440, here are decompositions:

  • 19 + 492421 = 492440
  • 31 + 492409 = 492440
  • 37 + 492403 = 492440
  • 43 + 492397 = 492440
  • 337 + 492103 = 492440
  • 373 + 492067 = 492440
  • 379 + 492061 = 492440
  • 433 + 492007 = 492440

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 492,440 and was likely granted around 1893.

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

Position in π

The digit sequence 492440 first appears in π at position 154,077 of the decimal expansion (the 154,077ordinal-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.
