Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6878, here are decompositions:

  • 7 + 6871 = 6878
  • 37 + 6841 = 6878
  • 97 + 6781 = 6878
  • 199 + 6679 = 6878
  • 241 + 6637 = 6878
  • 271 + 6607 = 6878
  • 307 + 6571 = 6878
  • 331 + 6547 = 6878

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6878 first appears in π at position 9,438 of the decimal expansion (the 9,438ordinal-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.
