Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169616, here are decompositions:

  • 127 + 169489 = 169616
  • 277 + 169339 = 169616
  • 367 + 169249 = 169616
  • 373 + 169243 = 169616
  • 397 + 169219 = 169616
  • 439 + 169177 = 169616
  • 457 + 169159 = 169616
  • 487 + 169129 = 169616

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 169,616 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 169616 first appears in π at position 220,842 of the decimal expansion (the 220,842ordinal-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.
