Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20260, here are decompositions:

  • 11 + 20249 = 20260
  • 29 + 20231 = 20260
  • 41 + 20219 = 20260
  • 59 + 20201 = 20260
  • 83 + 20177 = 20260
  • 113 + 20147 = 20260
  • 131 + 20129 = 20260
  • 137 + 20123 = 20260

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20260 first appears in π at position 3,118 of the decimal expansion (the 3,118ordinal-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.
