Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621284, here are decompositions:

  • 31 + 33621253 = 33621284
  • 373 + 33620911 = 33621284
  • 523 + 33620761 = 33621284
  • 577 + 33620707 = 33621284
  • 661 + 33620623 = 33621284
  • 691 + 33620593 = 33621284
  • 757 + 33620527 = 33621284
  • 811 + 33620473 = 33621284

Showing the first eight; more decompositions exist.
