Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10228, here are decompositions:

  • 5 + 10223 = 10228
  • 17 + 10211 = 10228
  • 47 + 10181 = 10228
  • 59 + 10169 = 10228
  • 89 + 10139 = 10228
  • 137 + 10091 = 10228
  • 149 + 10079 = 10228
  • 167 + 10061 = 10228

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10228 first appears in π at position 6,399 of the decimal expansion (the 6,399ordinal-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.
