Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536358, here are decompositions:

  • 5 + 31536353 = 31536358
  • 11 + 31536347 = 31536358
  • 71 + 31536287 = 31536358
  • 131 + 31536227 = 31536358
  • 197 + 31536161 = 31536358
  • 257 + 31536101 = 31536358
  • 419 + 31535939 = 31536358
  • 449 + 31535909 = 31536358

Showing the first eight; more decompositions exist.
