Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99400, here are decompositions:

  • 3 + 99397 = 99400
  • 23 + 99377 = 99400
  • 29 + 99371 = 99400
  • 53 + 99347 = 99400
  • 83 + 99317 = 99400
  • 149 + 99251 = 99400
  • 167 + 99233 = 99400
  • 227 + 99173 = 99400

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 99400 first appears in π at position 23,806 of the decimal expansion (the 23,806ordinal-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.
