Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612312, here are decompositions:

3 + 31612309 = 31612312
5 + 31612307 = 31612312
71 + 31612241 = 31612312
89 + 31612223 = 31612312
113 + 31612199 = 31612312
191 + 31612121 = 31612312
233 + 31612079 = 31612312
269 + 31612043 = 31612312

Showing the first eight; more decompositions exist.
