Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64618, here are decompositions:

  • 5 + 64613 = 64618
  • 17 + 64601 = 64618
  • 41 + 64577 = 64618
  • 167 + 64451 = 64618
  • 179 + 64439 = 64618
  • 317 + 64301 = 64618
  • 347 + 64271 = 64618
  • 401 + 64217 = 64618

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64618 first appears in π at position 52,361 of the decimal expansion (the 52,361ordinal-suffix:st 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.
