Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20622, here are decompositions:

  • 11 + 20611 = 20622
  • 23 + 20599 = 20622
  • 29 + 20593 = 20622
  • 59 + 20563 = 20622
  • 71 + 20551 = 20622
  • 73 + 20549 = 20622
  • 79 + 20543 = 20622
  • 89 + 20533 = 20622

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20622 first appears in π at position 163,140 of the decimal expansion (the 163,140ordinal-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.
