Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999370, here are decompositions:

  • 11 + 999359 = 999370
  • 41 + 999329 = 999370
  • 83 + 999287 = 999370
  • 101 + 999269 = 999370
  • 131 + 999239 = 999370
  • 137 + 999233 = 999370
  • 149 + 999221 = 999370
  • 269 + 999101 = 999370

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 999,370 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 999370 first appears in π at position 832,835 of the decimal expansion (the 832,835ordinal-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.
