Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612230, here are decompositions:

7 + 31612223 = 31612230
29 + 31612201 = 31612230
31 + 31612199 = 31612230
79 + 31612151 = 31612230
109 + 31612121 = 31612230
149 + 31612081 = 31612230
151 + 31612079 = 31612230
233 + 31611997 = 31612230

Showing the first eight; more decompositions exist.
