Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543644, here are decompositions:

  • 73 + 31543571 = 31543644
  • 101 + 31543543 = 31543644
  • 113 + 31543531 = 31543644
  • 163 + 31543481 = 31543644
  • 191 + 31543453 = 31543644
  • 193 + 31543451 = 31543644
  • 283 + 31543361 = 31543644
  • 313 + 31543331 = 31543644

Showing the first eight; more decompositions exist.
