Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186574, here are decompositions:

  • 5 + 186569 = 186574
  • 23 + 186551 = 186574
  • 137 + 186437 = 186574
  • 197 + 186377 = 186574
  • 257 + 186317 = 186574
  • 263 + 186311 = 186574
  • 347 + 186227 = 186574
  • 383 + 186191 = 186574

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 186,574 and was likely granted around 1875.

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

Position in π

The digit sequence 186574 first appears in π at position 289,494 of the decimal expansion (the 289,494ordinal-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.
