Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599830, here are decompositions:

  • 7 + 31599823 = 31599830
  • 19 + 31599811 = 31599830
  • 103 + 31599727 = 31599830
  • 127 + 31599703 = 31599830
  • 181 + 31599649 = 31599830
  • 277 + 31599553 = 31599830
  • 331 + 31599499 = 31599830
  • 523 + 31599307 = 31599830

Showing the first eight; more decompositions exist.
