Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33527990, here are decompositions:

  • 19 + 33527971 = 33527990
  • 43 + 33527947 = 33527990
  • 61 + 33527929 = 33527990
  • 103 + 33527887 = 33527990
  • 109 + 33527881 = 33527990
  • 127 + 33527863 = 33527990
  • 193 + 33527797 = 33527990
  • 241 + 33527749 = 33527990

Showing the first eight; more decompositions exist.
