Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612270, here are decompositions:

29 + 31612241 = 31612270
47 + 31612223 = 31612270
71 + 31612199 = 31612270
149 + 31612121 = 31612270
191 + 31612079 = 31612270
227 + 31612043 = 31612270
257 + 31612013 = 31612270
353 + 31611917 = 31612270

Showing the first eight; more decompositions exist.
