Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624570, here are decompositions:

  • 11 + 31624559 = 31624570
  • 23 + 31624547 = 31624570
  • 59 + 31624511 = 31624570
  • 113 + 31624457 = 31624570
  • 227 + 31624343 = 31624570
  • 233 + 31624337 = 31624570
  • 239 + 31624331 = 31624570
  • 293 + 31624277 = 31624570

Showing the first eight; more decompositions exist.
