Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612282, here are decompositions:

5 + 31612277 = 31612282
41 + 31612241 = 31612282
59 + 31612223 = 31612282
83 + 31612199 = 31612282
131 + 31612151 = 31612282
173 + 31612109 = 31612282
239 + 31612043 = 31612282
269 + 31612013 = 31612282

Showing the first eight; more decompositions exist.
