Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475320, here are decompositions:

  • 3 + 31475317 = 31475320
  • 89 + 31475231 = 31475320
  • 131 + 31475189 = 31475320
  • 179 + 31475141 = 31475320
  • 251 + 31475069 = 31475320
  • 311 + 31475009 = 31475320
  • 389 + 31474931 = 31475320
  • 491 + 31474829 = 31475320

Showing the first eight; more decompositions exist.
