Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523676, here are decompositions:

7 + 31523669 = 31523676
17 + 31523659 = 31523676
29 + 31523647 = 31523676
43 + 31523633 = 31523676
97 + 31523579 = 31523676
137 + 31523539 = 31523676
139 + 31523537 = 31523676
199 + 31523477 = 31523676

Showing the first eight; more decompositions exist.
