Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612356, here are decompositions:

5 + 31612351 = 31612356
43 + 31612313 = 31612356
47 + 31612309 = 31612356
79 + 31612277 = 31612356
157 + 31612199 = 31612356
277 + 31612079 = 31612356
313 + 31612043 = 31612356
359 + 31611997 = 31612356

Showing the first eight; more decompositions exist.
