Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529616, here are decompositions:

  • 23 + 31529593 = 31529616
  • 59 + 31529557 = 31529616
  • 109 + 31529507 = 31529616
  • 137 + 31529479 = 31529616
  • 257 + 31529359 = 31529616
  • 263 + 31529353 = 31529616
  • 269 + 31529347 = 31529616
  • 337 + 31529279 = 31529616

Showing the first eight; more decompositions exist.
