Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2662, here are decompositions:

  • 3 + 2659 = 2662
  • 5 + 2657 = 2662
  • 29 + 2633 = 2662
  • 41 + 2621 = 2662
  • 53 + 2609 = 2662
  • 71 + 2591 = 2662
  • 83 + 2579 = 2662
  • 113 + 2549 = 2662

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2662 first appears in π at position 19,049 of the decimal expansion (the 19,049ordinal-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.
