Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461190, here are decompositions:

  • 11 + 31461179 = 31461190
  • 17 + 31461173 = 31461190
  • 29 + 31461161 = 31461190
  • 41 + 31461149 = 31461190
  • 179 + 31461011 = 31461190
  • 239 + 31460951 = 31461190
  • 263 + 31460927 = 31461190
  • 311 + 31460879 = 31461190

Showing the first eight; more decompositions exist.
