Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531560, here are decompositions:

  • 19 + 33531541 = 33531560
  • 61 + 33531499 = 33531560
  • 109 + 33531451 = 33531560
  • 157 + 33531403 = 33531560
  • 163 + 33531397 = 33531560
  • 211 + 33531349 = 33531560
  • 241 + 33531319 = 33531560
  • 277 + 33531283 = 33531560

Showing the first eight; more decompositions exist.
