Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10778, here are decompositions:

  • 7 + 10771 = 10778
  • 67 + 10711 = 10778
  • 127 + 10651 = 10778
  • 139 + 10639 = 10778
  • 151 + 10627 = 10778
  • 181 + 10597 = 10778
  • 211 + 10567 = 10778
  • 277 + 10501 = 10778

Showing the first eight; more decompositions exist.
