Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597492, here are decompositions:

  • 239 + 31597253 = 31597492
  • 293 + 31597199 = 31597492
  • 449 + 31597043 = 31597492
  • 461 + 31597031 = 31597492
  • 569 + 31596923 = 31597492
  • 593 + 31596899 = 31597492
  • 653 + 31596839 = 31597492
  • 743 + 31596749 = 31597492

Showing the first eight; more decompositions exist.
