Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481640, here are decompositions:

  • 13 + 33481627 = 33481640
  • 43 + 33481597 = 33481640
  • 211 + 33481429 = 33481640
  • 271 + 33481369 = 33481640
  • 331 + 33481309 = 33481640
  • 349 + 33481291 = 33481640
  • 523 + 33481117 = 33481640
  • 541 + 33481099 = 33481640

Showing the first eight; more decompositions exist.
