Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53218, here are decompositions:

  • 17 + 53201 = 53218
  • 29 + 53189 = 53218
  • 47 + 53171 = 53218
  • 71 + 53147 = 53218
  • 89 + 53129 = 53218
  • 101 + 53117 = 53218
  • 131 + 53087 = 53218
  • 149 + 53069 = 53218

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 53218 first appears in π at position 104,111 of the decimal expansion (the 104,111ordinal-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.
