Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42590, here are decompositions:

  • 13 + 42577 = 42590
  • 19 + 42571 = 42590
  • 103 + 42487 = 42590
  • 127 + 42463 = 42590
  • 139 + 42451 = 42590
  • 157 + 42433 = 42590
  • 181 + 42409 = 42590
  • 193 + 42397 = 42590

Showing the first eight; more decompositions exist.
