Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495320, here are decompositions:

  • 47 + 31495273 = 31495320
  • 79 + 31495241 = 31495320
  • 107 + 31495213 = 31495320
  • 149 + 31495171 = 31495320
  • 163 + 31495157 = 31495320
  • 167 + 31495153 = 31495320
  • 173 + 31495147 = 31495320
  • 211 + 31495109 = 31495320

Showing the first eight; more decompositions exist.
