Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566396, here are decompositions:

7 + 31566389 = 31566396
13 + 31566383 = 31566396
19 + 31566377 = 31566396
47 + 31566349 = 31566396
67 + 31566329 = 31566396
79 + 31566317 = 31566396
97 + 31566299 = 31566396
107 + 31566289 = 31566396

Showing the first eight; more decompositions exist.
