Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6218, here are decompositions:

  • 7 + 6211 = 6218
  • 19 + 6199 = 6218
  • 67 + 6151 = 6218
  • 97 + 6121 = 6218
  • 127 + 6091 = 6218
  • 139 + 6079 = 6218
  • 151 + 6067 = 6218
  • 181 + 6037 = 6218

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6218 first appears in π at position 6,528 of the decimal expansion (the 6,528ordinal-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.
