Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522302, here are decompositions:

  • 5 + 31522297 = 31522302
  • 59 + 31522243 = 31522302
  • 61 + 31522241 = 31522302
  • 73 + 31522229 = 31522302
  • 83 + 31522219 = 31522302
  • 173 + 31522129 = 31522302
  • 199 + 31522103 = 31522302
  • 211 + 31522091 = 31522302

Showing the first eight; more decompositions exist.
