Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612254, here are decompositions:

13 + 31612241 = 31612254
31 + 31612223 = 31612254
53 + 31612201 = 31612254
103 + 31612151 = 31612254
173 + 31612081 = 31612254
211 + 31612043 = 31612254
241 + 31612013 = 31612254
257 + 31611997 = 31612254

Showing the first eight; more decompositions exist.
