Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531218, here are decompositions:

  • 31 + 33531187 = 33531218
  • 157 + 33531061 = 33531218
  • 199 + 33531019 = 33531218
  • 241 + 33530977 = 33531218
  • 541 + 33530677 = 33531218
  • 601 + 33530617 = 33531218
  • 661 + 33530557 = 33531218
  • 727 + 33530491 = 33531218

Showing the first eight; more decompositions exist.
