Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525412, here are decompositions:

  • 151 + 31525261 = 31525412
  • 199 + 31525213 = 31525412
  • 211 + 31525201 = 31525412
  • 229 + 31525183 = 31525412
  • 421 + 31524991 = 31525412
  • 619 + 31524793 = 31525412
  • 691 + 31524721 = 31525412
  • 739 + 31524673 = 31525412

Showing the first eight; more decompositions exist.
