Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612162, here are decompositions:

11 + 31612151 = 31612162
41 + 31612121 = 31612162
53 + 31612109 = 31612162
83 + 31612079 = 31612162
149 + 31612013 = 31612162
251 + 31611911 = 31612162
269 + 31611893 = 31612162
293 + 31611869 = 31612162

Showing the first eight; more decompositions exist.
