Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66068, here are decompositions:

  • 31 + 66037 = 66068
  • 139 + 65929 = 66068
  • 229 + 65839 = 66068
  • 241 + 65827 = 66068
  • 307 + 65761 = 66068
  • 337 + 65731 = 66068
  • 349 + 65719 = 66068
  • 367 + 65701 = 66068

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66068 first appears in π at position 120,979 of the decimal expansion (the 120,979ordinal-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.
