Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42530, here are decompositions:

  • 31 + 42499 = 42530
  • 43 + 42487 = 42530
  • 67 + 42463 = 42530
  • 73 + 42457 = 42530
  • 79 + 42451 = 42530
  • 97 + 42433 = 42530
  • 127 + 42403 = 42530
  • 139 + 42391 = 42530

Showing the first eight; more decompositions exist.
