Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18600, here are decompositions:

  • 7 + 18593 = 18600
  • 13 + 18587 = 18600
  • 17 + 18583 = 18600
  • 47 + 18553 = 18600
  • 59 + 18541 = 18600
  • 61 + 18539 = 18600
  • 79 + 18521 = 18600
  • 83 + 18517 = 18600

Showing the first eight; more decompositions exist.
