Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22820, here are decompositions:

  • 3 + 22817 = 22820
  • 13 + 22807 = 22820
  • 37 + 22783 = 22820
  • 43 + 22777 = 22820
  • 79 + 22741 = 22820
  • 103 + 22717 = 22820
  • 151 + 22669 = 22820
  • 181 + 22639 = 22820

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22820 first appears in π at position 19,768 of the decimal expansion (the 19,768ordinal-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.
