Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487960, here are decompositions:

  • 47 + 33487913 = 33487960
  • 53 + 33487907 = 33487960
  • 59 + 33487901 = 33487960
  • 83 + 33487877 = 33487960
  • 101 + 33487859 = 33487960
  • 113 + 33487847 = 33487960
  • 227 + 33487733 = 33487960
  • 353 + 33487607 = 33487960

Showing the first eight; more decompositions exist.
