Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526960, here are decompositions:

  • 7 + 31526953 = 31526960
  • 19 + 31526941 = 31526960
  • 61 + 31526899 = 31526960
  • 67 + 31526893 = 31526960
  • 79 + 31526881 = 31526960
  • 97 + 31526863 = 31526960
  • 151 + 31526809 = 31526960
  • 211 + 31526749 = 31526960

Showing the first eight; more decompositions exist.
