Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550376, here are decompositions:

  • 5 + 31550371 = 31550376
  • 19 + 31550357 = 31550376
  • 23 + 31550353 = 31550376
  • 37 + 31550339 = 31550376
  • 47 + 31550329 = 31550376
  • 89 + 31550287 = 31550376
  • 163 + 31550213 = 31550376
  • 197 + 31550179 = 31550376

Showing the first eight; more decompositions exist.
