Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621688, here are decompositions:

  • 59 + 33621629 = 33621688
  • 197 + 33621491 = 33621688
  • 251 + 33621437 = 33621688
  • 281 + 33621407 = 33621688
  • 389 + 33621299 = 33621688
  • 641 + 33621047 = 33621688
  • 761 + 33620927 = 33621688
  • 797 + 33620891 = 33621688

Showing the first eight; more decompositions exist.
