Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473256, here are decompositions:

  • 5 + 31473251 = 31473256
  • 47 + 31473209 = 31473256
  • 53 + 31473203 = 31473256
  • 83 + 31473173 = 31473256
  • 149 + 31473107 = 31473256
  • 173 + 31473083 = 31473256
  • 179 + 31473077 = 31473256
  • 293 + 31472963 = 31473256

Showing the first eight; more decompositions exist.
