Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64860, here are decompositions:

  • 7 + 64853 = 64860
  • 11 + 64849 = 64860
  • 43 + 64817 = 64860
  • 67 + 64793 = 64860
  • 79 + 64781 = 64860
  • 97 + 64763 = 64860
  • 113 + 64747 = 64860
  • 151 + 64709 = 64860

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64860 first appears in π at position 68,215 of the decimal expansion (the 68,215ordinal-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.
