Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20702, here are decompositions:

  • 61 + 20641 = 20702
  • 103 + 20599 = 20702
  • 109 + 20593 = 20702
  • 139 + 20563 = 20702
  • 151 + 20551 = 20702
  • 181 + 20521 = 20702
  • 193 + 20509 = 20702
  • 223 + 20479 = 20702

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20702 first appears in π at position 125,480 of the decimal expansion (the 125,480ordinal-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.
