Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612174, here are decompositions:

23 + 31612151 = 31612174
53 + 31612121 = 31612174
131 + 31612043 = 31612174
233 + 31611941 = 31612174
257 + 31611917 = 31612174
263 + 31611911 = 31612174
281 + 31611893 = 31612174
557 + 31611617 = 31612174

Showing the first eight; more decompositions exist.
