Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33570072, here are decompositions:

  • 5 + 33570067 = 33570072
  • 13 + 33570059 = 33570072
  • 23 + 33570049 = 33570072
  • 61 + 33570011 = 33570072
  • 139 + 33569933 = 33570072
  • 163 + 33569909 = 33570072
  • 229 + 33569843 = 33570072
  • 269 + 33569803 = 33570072

Showing the first eight; more decompositions exist.
