Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462018, here are decompositions:

  • 11 + 31462007 = 31462018
  • 41 + 31461977 = 31462018
  • 131 + 31461887 = 31462018
  • 167 + 31461851 = 31462018
  • 227 + 31461791 = 31462018
  • 239 + 31461779 = 31462018
  • 257 + 31461761 = 31462018
  • 281 + 31461737 = 31462018

Showing the first eight; more decompositions exist.
