Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612042, here are decompositions:

29 + 31612013 = 31612042
101 + 31611941 = 31612042
131 + 31611911 = 31612042
149 + 31611893 = 31612042
173 + 31611869 = 31612042
191 + 31611851 = 31612042
239 + 31611803 = 31612042
281 + 31611761 = 31612042

Showing the first eight; more decompositions exist.
