Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12548, here are decompositions:

  • 7 + 12541 = 12548
  • 31 + 12517 = 12548
  • 37 + 12511 = 12548
  • 61 + 12487 = 12548
  • 97 + 12451 = 12548
  • 127 + 12421 = 12548
  • 139 + 12409 = 12548
  • 157 + 12391 = 12548

Showing the first eight; more decompositions exist.
