Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612272, here are decompositions:

31 + 31612241 = 31612272
71 + 31612201 = 31612272
73 + 31612199 = 31612272
151 + 31612121 = 31612272
163 + 31612109 = 31612272
191 + 31612081 = 31612272
193 + 31612079 = 31612272
229 + 31612043 = 31612272

Showing the first eight; more decompositions exist.
