Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995440, here are decompositions:

  • 41 + 995399 = 995440
  • 53 + 995387 = 995440
  • 59 + 995381 = 995440
  • 71 + 995369 = 995440
  • 101 + 995339 = 995440
  • 113 + 995327 = 995440
  • 137 + 995303 = 995440
  • 167 + 995273 = 995440

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 995,440 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 995440 first appears in π at position 43,511 of the decimal expansion (the 43,511ordinal-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.
