Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183072, here are decompositions:

  • 5 + 183067 = 183072
  • 13 + 183059 = 183072
  • 31 + 183041 = 183072
  • 73 + 182999 = 183072
  • 103 + 182969 = 183072
  • 139 + 182933 = 183072
  • 151 + 182921 = 183072
  • 173 + 182899 = 183072

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 183,072 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 183072 first appears in π at position 642,862 of the decimal expansion (the 642,862ordinal-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.
