Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612236, here are decompositions:

13 + 31612223 = 31612236
37 + 31612199 = 31612236
127 + 31612109 = 31612236
157 + 31612079 = 31612236
167 + 31612069 = 31612236
193 + 31612043 = 31612236
223 + 31612013 = 31612236
239 + 31611997 = 31612236

Showing the first eight; more decompositions exist.
