Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486204, here are decompositions:

  • 3 + 31486201 = 31486204
  • 41 + 31486163 = 31486204
  • 83 + 31486121 = 31486204
  • 251 + 31485953 = 31486204
  • 263 + 31485941 = 31486204
  • 311 + 31485893 = 31486204
  • 401 + 31485803 = 31486204
  • 461 + 31485743 = 31486204

Showing the first eight; more decompositions exist.
