Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68506, here are decompositions:

  • 5 + 68501 = 68506
  • 17 + 68489 = 68506
  • 23 + 68483 = 68506
  • 29 + 68477 = 68506
  • 59 + 68447 = 68506
  • 107 + 68399 = 68506
  • 227 + 68279 = 68506
  • 293 + 68213 = 68506

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 68506 first appears in π at position 18,077 of the decimal expansion (the 18,077ordinal-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.
