Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592000, here are decompositions:

  • 3 + 31591997 = 31592000
  • 7 + 31591993 = 31592000
  • 43 + 31591957 = 31592000
  • 127 + 31591873 = 31592000
  • 157 + 31591843 = 31592000
  • 163 + 31591837 = 31592000
  • 277 + 31591723 = 31592000
  • 313 + 31591687 = 31592000

Showing the first eight; more decompositions exist.
