Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532212, here are decompositions:

  • 3 + 31532209 = 31532212
  • 71 + 31532141 = 31532212
  • 149 + 31532063 = 31532212
  • 191 + 31532021 = 31532212
  • 281 + 31531931 = 31532212
  • 461 + 31531751 = 31532212
  • 563 + 31531649 = 31532212
  • 809 + 31531403 = 31532212

Showing the first eight; more decompositions exist.
