Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612284, here are decompositions:

7 + 31612277 = 31612284
43 + 31612241 = 31612284
61 + 31612223 = 31612284
83 + 31612201 = 31612284
163 + 31612121 = 31612284
241 + 31612043 = 31612284
271 + 31612013 = 31612284
367 + 31611917 = 31612284

Showing the first eight; more decompositions exist.
