Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42826, here are decompositions:

  • 5 + 42821 = 42826
  • 29 + 42797 = 42826
  • 53 + 42773 = 42826
  • 59 + 42767 = 42826
  • 83 + 42743 = 42826
  • 89 + 42737 = 42826
  • 107 + 42719 = 42826
  • 137 + 42689 = 42826

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42826 first appears in π at position 328,059 of the decimal expansion (the 328,059ordinal-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.
