Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159188, here are decompositions:

  • 19 + 159169 = 159188
  • 31 + 159157 = 159188
  • 109 + 159079 = 159188
  • 229 + 158959 = 159188
  • 307 + 158881 = 159188
  • 397 + 158791 = 159188
  • 439 + 158749 = 159188
  • 457 + 158731 = 159188

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 159,188 and was likely granted around 1873.

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

Position in π

The digit sequence 159188 first appears in π at position 480,837 of the decimal expansion (the 480,837ordinal-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.
