Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112100, here are decompositions:

  • 3 + 112097 = 112100
  • 13 + 112087 = 112100
  • 31 + 112069 = 112100
  • 103 + 111997 = 112100
  • 127 + 111973 = 112100
  • 151 + 111949 = 112100
  • 181 + 111919 = 112100
  • 229 + 111871 = 112100

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 112,100 and was likely granted around 1871.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 112100 first appears in π at position 723,569 of the decimal expansion (the 723,569ordinal-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.
