Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545396, here are decompositions:

5 + 31545391 = 31545396
17 + 31545379 = 31545396
23 + 31545373 = 31545396
53 + 31545343 = 31545396
67 + 31545329 = 31545396
73 + 31545323 = 31545396
79 + 31545317 = 31545396
97 + 31545299 = 31545396

Showing the first eight; more decompositions exist.
