Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572660, here are decompositions:

  • 13 + 33572647 = 33572660
  • 31 + 33572629 = 33572660
  • 103 + 33572557 = 33572660
  • 127 + 33572533 = 33572660
  • 139 + 33572521 = 33572660
  • 157 + 33572503 = 33572660
  • 283 + 33572377 = 33572660
  • 307 + 33572353 = 33572660

Showing the first eight; more decompositions exist.
