Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612246, here are decompositions:

5 + 31612241 = 31612246
23 + 31612223 = 31612246
47 + 31612199 = 31612246
137 + 31612109 = 31612246
167 + 31612079 = 31612246
233 + 31612013 = 31612246
353 + 31611893 = 31612246
443 + 31611803 = 31612246

Showing the first eight; more decompositions exist.
