Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64480, here are decompositions:

  • 29 + 64451 = 64480
  • 41 + 64439 = 64480
  • 47 + 64433 = 64480
  • 107 + 64373 = 64480
  • 179 + 64301 = 64480
  • 197 + 64283 = 64480
  • 257 + 64223 = 64480
  • 263 + 64217 = 64480

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64480 first appears in π at position 91,782 of the decimal expansion (the 91,782ordinal-suffix:nd 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.
