Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472470, here are decompositions:

  • 131 + 31472339 = 31472470
  • 179 + 31472291 = 31472470
  • 269 + 31472201 = 31472470
  • 311 + 31472159 = 31472470
  • 317 + 31472153 = 31472470
  • 347 + 31472123 = 31472470
  • 401 + 31472069 = 31472470
  • 467 + 31472003 = 31472470

Showing the first eight; more decompositions exist.
