Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18554, here are decompositions:

  • 13 + 18541 = 18554
  • 31 + 18523 = 18554
  • 37 + 18517 = 18554
  • 61 + 18493 = 18554
  • 73 + 18481 = 18554
  • 97 + 18457 = 18554
  • 103 + 18451 = 18554
  • 127 + 18427 = 18554

Showing the first eight; more decompositions exist.
