Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536254, here are decompositions:

  • 31 + 31536223 = 31536254
  • 67 + 31536187 = 31536254
  • 157 + 31536097 = 31536254
  • 193 + 31536061 = 31536254
  • 271 + 31535983 = 31536254
  • 307 + 31535947 = 31536254
  • 313 + 31535941 = 31536254
  • 433 + 31535821 = 31536254

Showing the first eight; more decompositions exist.
