Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612324, here are decompositions:

11 + 31612313 = 31612324
17 + 31612307 = 31612324
47 + 31612277 = 31612324
83 + 31612241 = 31612324
101 + 31612223 = 31612324
173 + 31612151 = 31612324
281 + 31612043 = 31612324
311 + 31612013 = 31612324

Showing the first eight; more decompositions exist.
