Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627636, here are decompositions:

  • 59 + 31627577 = 31627636
  • 263 + 31627373 = 31627636
  • 317 + 31627319 = 31627636
  • 347 + 31627289 = 31627636
  • 389 + 31627247 = 31627636
  • 419 + 31627217 = 31627636
  • 503 + 31627133 = 31627636
  • 563 + 31627073 = 31627636

Showing the first eight; more decompositions exist.
