Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543234, here are decompositions:

  • 3 + 31543231 = 31543234
  • 11 + 31543223 = 31543234
  • 17 + 31543217 = 31543234
  • 53 + 31543181 = 31543234
  • 71 + 31543163 = 31543234
  • 101 + 31543133 = 31543234
  • 131 + 31543103 = 31543234
  • 167 + 31543067 = 31543234

Showing the first eight; more decompositions exist.
