Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473360, here are decompositions:

  • 29 + 31473331 = 31473360
  • 47 + 31473313 = 31473360
  • 97 + 31473263 = 31473360
  • 109 + 31473251 = 31473360
  • 151 + 31473209 = 31473360
  • 157 + 31473203 = 31473360
  • 173 + 31473187 = 31473360
  • 197 + 31473163 = 31473360

Showing the first eight; more decompositions exist.
