Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556520, here are decompositions:

  • 13 + 33556507 = 33556520
  • 37 + 33556483 = 33556520
  • 61 + 33556459 = 33556520
  • 97 + 33556423 = 33556520
  • 139 + 33556381 = 33556520
  • 163 + 33556357 = 33556520
  • 181 + 33556339 = 33556520
  • 313 + 33556207 = 33556520

Showing the first eight; more decompositions exist.
