Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7628, here are decompositions:

  • 7 + 7621 = 7628
  • 37 + 7591 = 7628
  • 67 + 7561 = 7628
  • 79 + 7549 = 7628
  • 139 + 7489 = 7628
  • 151 + 7477 = 7628
  • 211 + 7417 = 7628
  • 277 + 7351 = 7628

Showing the first eight; more decompositions exist.
