Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495266, here are decompositions:

  • 53 + 31495213 = 31495266
  • 67 + 31495199 = 31495266
  • 79 + 31495187 = 31495266
  • 109 + 31495157 = 31495266
  • 113 + 31495153 = 31495266
  • 149 + 31495117 = 31495266
  • 157 + 31495109 = 31495266
  • 223 + 31495043 = 31495266

Showing the first eight; more decompositions exist.
