Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612204, here are decompositions:

3 + 31612201 = 31612204
5 + 31612199 = 31612204
53 + 31612151 = 31612204
83 + 31612121 = 31612204
191 + 31612013 = 31612204
263 + 31611941 = 31612204
293 + 31611911 = 31612204
311 + 31611893 = 31612204

Showing the first eight; more decompositions exist.
