Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33626440, here are decompositions:

  • 101 + 33626339 = 33626440
  • 131 + 33626309 = 33626440
  • 173 + 33626267 = 33626440
  • 191 + 33626249 = 33626440
  • 227 + 33626213 = 33626440
  • 347 + 33626093 = 33626440
  • 383 + 33626057 = 33626440
  • 479 + 33625961 = 33626440

Showing the first eight; more decompositions exist.
