Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42536, here are decompositions:

  • 3 + 42533 = 42536
  • 37 + 42499 = 42536
  • 73 + 42463 = 42536
  • 79 + 42457 = 42536
  • 103 + 42433 = 42536
  • 127 + 42409 = 42536
  • 139 + 42397 = 42536
  • 157 + 42379 = 42536

Showing the first eight; more decompositions exist.
