Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471620, here are decompositions:

  • 3 + 471617 = 471620
  • 13 + 471607 = 471620
  • 31 + 471589 = 471620
  • 67 + 471553 = 471620
  • 139 + 471481 = 471620
  • 181 + 471439 = 471620
  • 229 + 471391 = 471620
  • 307 + 471313 = 471620

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 471,620 and was likely granted around 1891.

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

Position in π

The digit sequence 471620 first appears in π at position 374,307 of the decimal expansion (the 374,307ordinal-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.
