Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180606, here are decompositions:

  • 37 + 180569 = 180606
  • 43 + 180563 = 180606
  • 59 + 180547 = 180606
  • 67 + 180539 = 180606
  • 73 + 180533 = 180606
  • 103 + 180503 = 180606
  • 109 + 180497 = 180606
  • 193 + 180413 = 180606

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 180,606 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 180606 first appears in π at position 566,730 of the decimal expansion (the 566,730ordinal-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.
