Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529514, here are decompositions:

  • 7 + 31529507 = 31529514
  • 43 + 31529471 = 31529514
  • 67 + 31529447 = 31529514
  • 83 + 31529431 = 31529514
  • 101 + 31529413 = 31529514
  • 167 + 31529347 = 31529514
  • 193 + 31529321 = 31529514
  • 241 + 31529273 = 31529514

Showing the first eight; more decompositions exist.
