Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67520, here are decompositions:

  • 31 + 67489 = 67520
  • 43 + 67477 = 67520
  • 67 + 67453 = 67520
  • 73 + 67447 = 67520
  • 109 + 67411 = 67520
  • 151 + 67369 = 67520
  • 181 + 67339 = 67520
  • 307 + 67213 = 67520

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 67520 first appears in π at position 7,232 of the decimal expansion (the 7,232ordinal-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.
