Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64470, here are decompositions:

  • 17 + 64453 = 64470
  • 19 + 64451 = 64470
  • 31 + 64439 = 64470
  • 37 + 64433 = 64470
  • 67 + 64403 = 64470
  • 71 + 64399 = 64470
  • 89 + 64381 = 64470
  • 97 + 64373 = 64470

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64470 first appears in π at position 3,371 of the decimal expansion (the 3,371ordinal-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.
