Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8480, here are decompositions:

  • 13 + 8467 = 8480
  • 19 + 8461 = 8480
  • 37 + 8443 = 8480
  • 61 + 8419 = 8480
  • 103 + 8377 = 8480
  • 127 + 8353 = 8480
  • 151 + 8329 = 8480
  • 163 + 8317 = 8480

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8480 first appears in π at position 21,755 of the decimal expansion (the 21,755ordinal-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.
