Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617924, here are decompositions:

47 + 31617877 = 31617924
53 + 31617871 = 31617924
61 + 31617863 = 31617924
71 + 31617853 = 31617924
97 + 31617827 = 31617924
113 + 31617811 = 31617924
127 + 31617797 = 31617924
167 + 31617757 = 31617924

Showing the first eight; more decompositions exist.
