Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991196, here are decompositions:

  • 67 + 991129 = 991196
  • 127 + 991069 = 991196
  • 139 + 991057 = 991196
  • 223 + 990973 = 991196
  • 229 + 990967 = 991196
  • 307 + 990889 = 991196
  • 397 + 990799 = 991196
  • 463 + 990733 = 991196

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 991,196 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 991196 first appears in π at position 155,220 of the decimal expansion (the 155,220ordinal-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.
