Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529308, here are decompositions:

  • 29 + 31529279 = 31529308
  • 59 + 31529249 = 31529308
  • 89 + 31529219 = 31529308
  • 227 + 31529081 = 31529308
  • 311 + 31528997 = 31529308
  • 467 + 31528841 = 31529308
  • 557 + 31528751 = 31529308
  • 761 + 31528547 = 31529308

Showing the first eight; more decompositions exist.
