Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20230, here are decompositions:

  • 11 + 20219 = 20230
  • 29 + 20201 = 20230
  • 47 + 20183 = 20230
  • 53 + 20177 = 20230
  • 83 + 20147 = 20230
  • 101 + 20129 = 20230
  • 107 + 20123 = 20230
  • 113 + 20117 = 20230

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20230 first appears in π at position 210,128 of the decimal expansion (the 210,128ordinal-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.
