Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612510, here are decompositions:

23 + 31612487 = 31612510
29 + 31612481 = 31612510
197 + 31612313 = 31612510
233 + 31612277 = 31612510
269 + 31612241 = 31612510
311 + 31612199 = 31612510
359 + 31612151 = 31612510
389 + 31612121 = 31612510

Showing the first eight; more decompositions exist.
