Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612242, here are decompositions:

19 + 31612223 = 31612242
41 + 31612201 = 31612242
43 + 31612199 = 31612242
163 + 31612079 = 31612242
173 + 31612069 = 31612242
199 + 31612043 = 31612242
229 + 31612013 = 31612242
331 + 31611911 = 31612242

Showing the first eight; more decompositions exist.
