Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660538, here are decompositions:

  • 11 + 8660527 = 8660538
  • 31 + 8660507 = 8660538
  • 71 + 8660467 = 8660538
  • 101 + 8660437 = 8660538
  • 137 + 8660401 = 8660538
  • 151 + 8660387 = 8660538
  • 157 + 8660381 = 8660538
  • 199 + 8660339 = 8660538

Showing the first eight; more decompositions exist.
