Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64564, here are decompositions:

  • 11 + 64553 = 64564
  • 113 + 64451 = 64564
  • 131 + 64433 = 64564
  • 191 + 64373 = 64564
  • 263 + 64301 = 64564
  • 281 + 64283 = 64564
  • 293 + 64271 = 64564
  • 347 + 64217 = 64564

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64564 first appears in π at position 14,345 of the decimal expansion (the 14,345ordinal-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.
