Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523016, here are decompositions:

13 + 31523003 = 31523016
29 + 31522987 = 31523016
37 + 31522979 = 31523016
79 + 31522937 = 31523016
127 + 31522889 = 31523016
193 + 31522823 = 31523016
269 + 31522747 = 31523016
347 + 31522669 = 31523016

Showing the first eight; more decompositions exist.
