Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78516, here are decompositions:

  • 5 + 78511 = 78516
  • 7 + 78509 = 78516
  • 19 + 78497 = 78516
  • 29 + 78487 = 78516
  • 37 + 78479 = 78516
  • 79 + 78437 = 78516
  • 89 + 78427 = 78516
  • 149 + 78367 = 78516

Showing the first eight; more decompositions exist.
