Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533060, here are decompositions:

  • 47 + 31533013 = 31533060
  • 59 + 31533001 = 31533060
  • 61 + 31532999 = 31533060
  • 79 + 31532981 = 31533060
  • 89 + 31532971 = 31533060
  • 101 + 31532959 = 31533060
  • 137 + 31532923 = 31533060
  • 179 + 31532881 = 31533060

Showing the first eight; more decompositions exist.
