Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595212, here are decompositions:

  • 3 + 31595209 = 31595212
  • 23 + 31595189 = 31595212
  • 71 + 31595141 = 31595212
  • 149 + 31595063 = 31595212
  • 191 + 31595021 = 31595212
  • 251 + 31594961 = 31595212
  • 281 + 31594931 = 31595212
  • 293 + 31594919 = 31595212

Showing the first eight; more decompositions exist.
