Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543210, here are decompositions:

  • 3 + 31543207 = 31543210
  • 29 + 31543181 = 31543210
  • 47 + 31543163 = 31543210
  • 107 + 31543103 = 31543210
  • 131 + 31543079 = 31543210
  • 191 + 31543019 = 31543210
  • 239 + 31542971 = 31543210
  • 269 + 31542941 = 31543210

Showing the first eight; more decompositions exist.
