Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10102, here are decompositions:

  • 3 + 10099 = 10102
  • 11 + 10091 = 10102
  • 23 + 10079 = 10102
  • 41 + 10061 = 10102
  • 173 + 9929 = 10102
  • 179 + 9923 = 10102
  • 251 + 9851 = 10102
  • 263 + 9839 = 10102

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10102 first appears in π at position 19,803 of the decimal expansion (the 19,803ordinal-suffix:rd 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.
