Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624136, here are decompositions:

  • 7 + 31624129 = 31624136
  • 67 + 31624069 = 31624136
  • 157 + 31623979 = 31624136
  • 433 + 31623703 = 31624136
  • 547 + 31623589 = 31624136
  • 613 + 31623523 = 31624136
  • 937 + 31623199 = 31624136
  • 967 + 31623169 = 31624136

Showing the first eight; more decompositions exist.
