Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187038, here are decompositions:

  • 11 + 187027 = 187038
  • 29 + 187009 = 187038
  • 79 + 186959 = 187038
  • 149 + 186889 = 187038
  • 167 + 186871 = 187038
  • 179 + 186859 = 187038
  • 197 + 186841 = 187038
  • 239 + 186799 = 187038

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 187,038 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 187038 first appears in π at position 88,562 of the decimal expansion (the 88,562ordinal-suffix:nd 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.
