Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600038, here are decompositions:

  • 37 + 31600001 = 31600038
  • 61 + 31599977 = 31600038
  • 79 + 31599959 = 31600038
  • 97 + 31599941 = 31600038
  • 109 + 31599929 = 31600038
  • 137 + 31599901 = 31600038
  • 167 + 31599871 = 31600038
  • 179 + 31599859 = 31600038

Showing the first eight; more decompositions exist.
