Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532088, here are decompositions:

  • 17 + 31532071 = 31532088
  • 67 + 31532021 = 31532088
  • 157 + 31531931 = 31532088
  • 167 + 31531921 = 31532088
  • 179 + 31531909 = 31532088
  • 271 + 31531817 = 31532088
  • 337 + 31531751 = 31532088
  • 409 + 31531679 = 31532088

Showing the first eight; more decompositions exist.
