Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498306, here are decompositions:

  • 17 + 31498289 = 31498306
  • 29 + 31498277 = 31498306
  • 53 + 31498253 = 31498306
  • 89 + 31498217 = 31498306
  • 107 + 31498199 = 31498306
  • 113 + 31498193 = 31498306
  • 263 + 31498043 = 31498306
  • 443 + 31497863 = 31498306

Showing the first eight; more decompositions exist.
