Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612060, here are decompositions:

17 + 31612043 = 31612060
47 + 31612013 = 31612060
149 + 31611911 = 31612060
167 + 31611893 = 31612060
191 + 31611869 = 31612060
257 + 31611803 = 31612060
401 + 31611659 = 31612060
419 + 31611641 = 31612060

Showing the first eight; more decompositions exist.
