Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68888, here are decompositions:

  • 7 + 68881 = 68888
  • 67 + 68821 = 68888
  • 97 + 68791 = 68888
  • 139 + 68749 = 68888
  • 151 + 68737 = 68888
  • 229 + 68659 = 68888
  • 277 + 68611 = 68888
  • 307 + 68581 = 68888

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 68888 first appears in π at position 59,549 of the decimal expansion (the 59,549ordinal-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.
