Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109280, here are decompositions:

  • 13 + 109267 = 109280
  • 79 + 109201 = 109280
  • 109 + 109171 = 109280
  • 139 + 109141 = 109280
  • 313 + 108967 = 109280
  • 331 + 108949 = 109280
  • 337 + 108943 = 109280
  • 373 + 108907 = 109280

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 109,280 and was likely granted around 1871.

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

Position in π

The digit sequence 109280 first appears in π at position 141,905 of the decimal expansion (the 141,905ordinal-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.
