Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495338, here are decompositions:

  • 5 + 31495333 = 31495338
  • 97 + 31495241 = 31495338
  • 139 + 31495199 = 31495338
  • 151 + 31495187 = 31495338
  • 167 + 31495171 = 31495338
  • 181 + 31495157 = 31495338
  • 191 + 31495147 = 31495338
  • 229 + 31495109 = 31495338

Showing the first eight; more decompositions exist.
