Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161302, here are decompositions:

  • 101 + 161201 = 161302
  • 179 + 161123 = 161302
  • 263 + 161039 = 161302
  • 269 + 161033 = 161302
  • 293 + 161009 = 161302
  • 419 + 160883 = 161302
  • 461 + 160841 = 161302
  • 521 + 160781 = 161302

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 161,302 and was likely granted around 1874.

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

Position in π

The digit sequence 161302 first appears in π at position 513,286 of the decimal expansion (the 513,286ordinal-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.
