Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6920, here are decompositions:

  • 3 + 6917 = 6920
  • 13 + 6907 = 6920
  • 37 + 6883 = 6920
  • 79 + 6841 = 6920
  • 97 + 6823 = 6920
  • 127 + 6793 = 6920
  • 139 + 6781 = 6920
  • 157 + 6763 = 6920

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6920 first appears in π at position 8,300 of the decimal expansion (the 8,300ordinal-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.
