Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612488, here are decompositions:

7 + 31612481 = 31612488
59 + 31612429 = 31612488
97 + 31612391 = 31612488
107 + 31612381 = 31612488
137 + 31612351 = 31612488
179 + 31612309 = 31612488
181 + 31612307 = 31612488
211 + 31612277 = 31612488

Showing the first eight; more decompositions exist.
