Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457426, here are decompositions:

  • 43 + 31457383 = 31457426
  • 79 + 31457347 = 31457426
  • 97 + 31457329 = 31457426
  • 139 + 31457287 = 31457426
  • 157 + 31457269 = 31457426
  • 199 + 31457227 = 31457426
  • 223 + 31457203 = 31457426
  • 277 + 31457149 = 31457426

Showing the first eight; more decompositions exist.
