Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33570940, here are decompositions:

  • 41 + 33570899 = 33570940
  • 59 + 33570881 = 33570940
  • 89 + 33570851 = 33570940
  • 107 + 33570833 = 33570940
  • 131 + 33570809 = 33570940
  • 191 + 33570749 = 33570940
  • 251 + 33570689 = 33570940
  • 317 + 33570623 = 33570940

Showing the first eight; more decompositions exist.
