Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612228, here are decompositions:

5 + 31612223 = 31612228
29 + 31612199 = 31612228
107 + 31612121 = 31612228
149 + 31612079 = 31612228
311 + 31611917 = 31612228
317 + 31611911 = 31612228
359 + 31611869 = 31612228
467 + 31611761 = 31612228

Showing the first eight; more decompositions exist.
