Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529506, here are decompositions:

  • 59 + 31529447 = 31529506
  • 227 + 31529279 = 31529506
  • 233 + 31529273 = 31529506
  • 257 + 31529249 = 31529506
  • 263 + 31529243 = 31529506
  • 293 + 31529213 = 31529506
  • 419 + 31529087 = 31529506
  • 509 + 31528997 = 31529506

Showing the first eight; more decompositions exist.
