Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66368, here are decompositions:

  • 7 + 66361 = 66368
  • 31 + 66337 = 66368
  • 67 + 66301 = 66368
  • 97 + 66271 = 66368
  • 199 + 66169 = 66368
  • 331 + 66037 = 66368
  • 439 + 65929 = 66368
  • 487 + 65881 = 66368

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66368 first appears in π at position 241,646 of the decimal expansion (the 241,646ordinal-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.
