Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585032, here are decompositions:

  • 13 + 31585019 = 31585032
  • 71 + 31584961 = 31585032
  • 79 + 31584953 = 31585032
  • 131 + 31584901 = 31585032
  • 151 + 31584881 = 31585032
  • 163 + 31584869 = 31585032
  • 179 + 31584853 = 31585032
  • 223 + 31584809 = 31585032

Showing the first eight; more decompositions exist.
