Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522200, here are decompositions:

  • 19 + 31522181 = 31522200
  • 71 + 31522129 = 31522200
  • 97 + 31522103 = 31522200
  • 109 + 31522091 = 31522200
  • 139 + 31522061 = 31522200
  • 179 + 31522021 = 31522200
  • 181 + 31522019 = 31522200
  • 223 + 31521977 = 31522200

Showing the first eight; more decompositions exist.
