Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627666, here are decompositions:

  • 17 + 31627649 = 31627666
  • 89 + 31627577 = 31627666
  • 107 + 31627559 = 31627666
  • 293 + 31627373 = 31627666
  • 347 + 31627319 = 31627666
  • 419 + 31627247 = 31627666
  • 449 + 31627217 = 31627666
  • 593 + 31627073 = 31627666

Showing the first eight; more decompositions exist.
