Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161282, here are decompositions:

  • 19 + 161263 = 161282
  • 61 + 161221 = 161282
  • 211 + 161071 = 161282
  • 223 + 161059 = 161282
  • 229 + 161053 = 161282
  • 313 + 160969 = 161282
  • 349 + 160933 = 161282
  • 379 + 160903 = 161282

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 161,282 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 161282 first appears in π at position 905,790 of the decimal expansion (the 905,790ordinal-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.
