Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995840, here are decompositions:

  • 7 + 995833 = 995840
  • 103 + 995737 = 995840
  • 127 + 995713 = 995840
  • 163 + 995677 = 995840
  • 199 + 995641 = 995840
  • 229 + 995611 = 995840
  • 379 + 995461 = 995840
  • 397 + 995443 = 995840

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 995,840 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 995840 first appears in π at position 943,036 of the decimal expansion (the 943,036ordinal-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.
