Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612132, here are decompositions:

11 + 31612121 = 31612132
23 + 31612109 = 31612132
53 + 31612079 = 31612132
89 + 31612043 = 31612132
191 + 31611941 = 31612132
239 + 31611893 = 31612132
263 + 31611869 = 31612132
281 + 31611851 = 31612132

Showing the first eight; more decompositions exist.
