Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190100, here are decompositions:

  • 3 + 190097 = 190100
  • 7 + 190093 = 190100
  • 37 + 190063 = 190100
  • 73 + 190027 = 190100
  • 103 + 189997 = 190100
  • 139 + 189961 = 190100
  • 151 + 189949 = 190100
  • 199 + 189901 = 190100

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 190,100 and was likely granted around 1875.

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

Position in π

The digit sequence 190100 first appears in π at position 255,170 of the decimal expansion (the 255,170ordinal-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.
