Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520960, here are decompositions:

  • 41 + 33520919 = 33520960
  • 101 + 33520859 = 33520960
  • 113 + 33520847 = 33520960
  • 131 + 33520829 = 33520960
  • 197 + 33520763 = 33520960
  • 251 + 33520709 = 33520960
  • 293 + 33520667 = 33520960
  • 311 + 33520649 = 33520960

Showing the first eight; more decompositions exist.
