Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624862, here are decompositions:

  • 13 + 31624849 = 31624862
  • 79 + 31624783 = 31624862
  • 109 + 31624753 = 31624862
  • 163 + 31624699 = 31624862
  • 223 + 31624639 = 31624862
  • 271 + 31624591 = 31624862
  • 433 + 31624429 = 31624862
  • 439 + 31624423 = 31624862

Showing the first eight; more decompositions exist.
