Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597630, here are decompositions:

  • 17 + 31597613 = 31597630
  • 59 + 31597571 = 31597630
  • 89 + 31597541 = 31597630
  • 137 + 31597493 = 31597630
  • 263 + 31597367 = 31597630
  • 293 + 31597337 = 31597630
  • 347 + 31597283 = 31597630
  • 431 + 31597199 = 31597630

Showing the first eight; more decompositions exist.
