Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615716, here are decompositions:

5 + 31615711 = 31615716
47 + 31615669 = 31615716
53 + 31615663 = 31615716
107 + 31615609 = 31615716
113 + 31615603 = 31615716
127 + 31615589 = 31615716
173 + 31615543 = 31615716
227 + 31615489 = 31615716

Showing the first eight; more decompositions exist.
