Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628362, here are decompositions:

  • 11 + 31628351 = 31628362
  • 71 + 31628291 = 31628362
  • 89 + 31628273 = 31628362
  • 113 + 31628249 = 31628362
  • 191 + 31628171 = 31628362
  • 263 + 31628099 = 31628362
  • 383 + 31627979 = 31628362
  • 401 + 31627961 = 31628362

Showing the first eight; more decompositions exist.
