Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999156, here are decompositions:

  • 7 + 999149 = 999156
  • 23 + 999133 = 999156
  • 73 + 999083 = 999156
  • 89 + 999067 = 999156
  • 107 + 999049 = 999156
  • 113 + 999043 = 999156
  • 127 + 999029 = 999156
  • 149 + 999007 = 999156

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 999,156 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 999156 first appears in π at position 109,485 of the decimal expansion (the 109,485ordinal-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.
