Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496078, here are decompositions:

  • 37 + 31496041 = 31496078
  • 67 + 31496011 = 31496078
  • 157 + 31495921 = 31496078
  • 181 + 31495897 = 31496078
  • 199 + 31495879 = 31496078
  • 277 + 31495801 = 31496078
  • 337 + 31495741 = 31496078
  • 349 + 31495729 = 31496078

Showing the first eight; more decompositions exist.
