Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474488, here are decompositions:

  • 7 + 31474481 = 31474488
  • 131 + 31474357 = 31474488
  • 137 + 31474351 = 31474488
  • 181 + 31474307 = 31474488
  • 197 + 31474291 = 31474488
  • 239 + 31474249 = 31474488
  • 271 + 31474217 = 31474488
  • 317 + 31474171 = 31474488

Showing the first eight; more decompositions exist.
