Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621154, here are decompositions:

  • 5 + 33621149 = 33621154
  • 41 + 33621113 = 33621154
  • 71 + 33621083 = 33621154
  • 107 + 33621047 = 33621154
  • 227 + 33620927 = 33621154
  • 263 + 33620891 = 33621154
  • 557 + 33620597 = 33621154
  • 563 + 33620591 = 33621154

Showing the first eight; more decompositions exist.
