Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457360, here are decompositions:

  • 13 + 31457347 = 31457360
  • 19 + 31457341 = 31457360
  • 31 + 31457329 = 31457360
  • 73 + 31457287 = 31457360
  • 157 + 31457203 = 31457360
  • 211 + 31457149 = 31457360
  • 241 + 31457119 = 31457360
  • 433 + 31456927 = 31457360

Showing the first eight; more decompositions exist.
