Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57220, here are decompositions:

  • 17 + 57203 = 57220
  • 29 + 57191 = 57220
  • 41 + 57179 = 57220
  • 47 + 57173 = 57220
  • 71 + 57149 = 57220
  • 89 + 57131 = 57220
  • 101 + 57119 = 57220
  • 113 + 57107 = 57220

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 57220 first appears in π at position 3,387 of the decimal expansion (the 3,387ordinal-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.
