Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689688, here are decompositions:

  • 31 + 8689657 = 8689688
  • 61 + 8689627 = 8689688
  • 79 + 8689609 = 8689688
  • 97 + 8689591 = 8689688
  • 151 + 8689537 = 8689688
  • 199 + 8689489 = 8689688
  • 367 + 8689321 = 8689688
  • 379 + 8689309 = 8689688

Showing the first eight; more decompositions exist.
