Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81834, here are decompositions:

  • 17 + 81817 = 81834
  • 61 + 81773 = 81834
  • 73 + 81761 = 81834
  • 97 + 81737 = 81834
  • 107 + 81727 = 81834
  • 127 + 81707 = 81834
  • 131 + 81703 = 81834
  • 157 + 81677 = 81834

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 81834 first appears in π at position 1,538 of the decimal expansion (the 1,538ordinal-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.
