Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486390, here are decompositions:

  • 11 + 486379 = 486390
  • 13 + 486377 = 486390
  • 41 + 486349 = 486390
  • 59 + 486331 = 486390
  • 61 + 486329 = 486390
  • 67 + 486323 = 486390
  • 83 + 486307 = 486390
  • 97 + 486293 = 486390

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 486,390 and was likely granted around 1892.

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

Position in π

The digit sequence 486390 first appears in π at position 764,927 of the decimal expansion (the 764,927ordinal-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.
