Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612210, here are decompositions:

11 + 31612199 = 31612210
59 + 31612151 = 31612210
89 + 31612121 = 31612210
101 + 31612109 = 31612210
131 + 31612079 = 31612210
167 + 31612043 = 31612210
197 + 31612013 = 31612210
269 + 31611941 = 31612210

Showing the first eight; more decompositions exist.
