Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531120, here are decompositions:

  • 23 + 33531097 = 33531120
  • 37 + 33531083 = 33531120
  • 43 + 33531077 = 33531120
  • 59 + 33531061 = 33531120
  • 61 + 33531059 = 33531120
  • 71 + 33531049 = 33531120
  • 89 + 33531031 = 33531120
  • 101 + 33531019 = 33531120

Showing the first eight; more decompositions exist.
