Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474486, here are decompositions:

  • 5 + 31474481 = 31474486
  • 53 + 31474433 = 31474486
  • 83 + 31474403 = 31474486
  • 89 + 31474397 = 31474486
  • 167 + 31474319 = 31474486
  • 179 + 31474307 = 31474486
  • 233 + 31474253 = 31474486
  • 269 + 31474217 = 31474486

Showing the first eight; more decompositions exist.
