Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522248, here are decompositions:

  • 5 + 31522243 = 31522248
  • 7 + 31522241 = 31522248
  • 19 + 31522229 = 31522248
  • 29 + 31522219 = 31522248
  • 41 + 31522207 = 31522248
  • 67 + 31522181 = 31522248
  • 157 + 31522091 = 31522248
  • 227 + 31522021 = 31522248

Showing the first eight; more decompositions exist.
