Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543630, here are decompositions:

  • 59 + 31543571 = 31543630
  • 101 + 31543529 = 31543630
  • 149 + 31543481 = 31543630
  • 179 + 31543451 = 31543630
  • 233 + 31543397 = 31543630
  • 269 + 31543361 = 31543630
  • 281 + 31543349 = 31543630
  • 449 + 31543181 = 31543630

Showing the first eight; more decompositions exist.
