Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542412, here are decompositions:

  • 53 + 31542359 = 31542412
  • 71 + 31542341 = 31542412
  • 89 + 31542323 = 31542412
  • 131 + 31542281 = 31542412
  • 179 + 31542233 = 31542412
  • 263 + 31542149 = 31542412
  • 389 + 31542023 = 31542412
  • 401 + 31542011 = 31542412

Showing the first eight; more decompositions exist.
