Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523220, here are decompositions:

  • 79 + 33523141 = 33523220
  • 193 + 33523027 = 33523220
  • 307 + 33522913 = 33523220
  • 673 + 33522547 = 33523220
  • 751 + 33522469 = 33523220
  • 769 + 33522451 = 33523220
  • 919 + 33522301 = 33523220
  • 1009 + 33522211 = 33523220

Showing the first eight; more decompositions exist.
