Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10642, here are decompositions:

  • 3 + 10639 = 10642
  • 11 + 10631 = 10642
  • 29 + 10613 = 10642
  • 41 + 10601 = 10642
  • 53 + 10589 = 10642
  • 83 + 10559 = 10642
  • 113 + 10529 = 10642
  • 179 + 10463 = 10642

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10642 first appears in π at position 7,353 of the decimal expansion (the 7,353ordinal-suffix:rd 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.
