Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42624, here are decompositions:

  • 13 + 42611 = 42624
  • 47 + 42577 = 42624
  • 53 + 42571 = 42624
  • 67 + 42557 = 42624
  • 137 + 42487 = 42624
  • 151 + 42473 = 42624
  • 157 + 42467 = 42624
  • 163 + 42461 = 42624

Showing the first eight; more decompositions exist.
