Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33619720, here are decompositions:

  • 47 + 33619673 = 33619720
  • 53 + 33619667 = 33619720
  • 131 + 33619589 = 33619720
  • 179 + 33619541 = 33619720
  • 191 + 33619529 = 33619720
  • 257 + 33619463 = 33619720
  • 269 + 33619451 = 33619720
  • 293 + 33619427 = 33619720

Showing the first eight; more decompositions exist.
