Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625646, here are decompositions:

  • 5 + 8625641 = 8625646
  • 47 + 8625599 = 8625646
  • 59 + 8625587 = 8625646
  • 137 + 8625509 = 8625646
  • 167 + 8625479 = 8625646
  • 179 + 8625467 = 8625646
  • 383 + 8625263 = 8625646
  • 443 + 8625203 = 8625646

Showing the first eight; more decompositions exist.
