Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621254, here are decompositions:

  • 3 + 33621251 = 33621254
  • 223 + 33621031 = 33621254
  • 397 + 33620857 = 33621254
  • 487 + 33620767 = 33621254
  • 547 + 33620707 = 33621254
  • 631 + 33620623 = 33621254
  • 661 + 33620593 = 33621254
  • 691 + 33620563 = 33621254

Showing the first eight; more decompositions exist.
