Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543252, here are decompositions:

  • 29 + 31543223 = 31543252
  • 71 + 31543181 = 31543252
  • 89 + 31543163 = 31543252
  • 149 + 31543103 = 31543252
  • 173 + 31543079 = 31543252
  • 233 + 31543019 = 31543252
  • 281 + 31542971 = 31543252
  • 311 + 31542941 = 31543252

Showing the first eight; more decompositions exist.
