Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462090, here are decompositions:

  • 83 + 31462007 = 31462090
  • 113 + 31461977 = 31462090
  • 167 + 31461923 = 31462090
  • 197 + 31461893 = 31462090
  • 239 + 31461851 = 31462090
  • 311 + 31461779 = 31462090
  • 347 + 31461743 = 31462090
  • 353 + 31461737 = 31462090

Showing the first eight; more decompositions exist.
