Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611042, here are decompositions:

5 + 31611037 = 31611042
13 + 31611029 = 31611042
19 + 31611023 = 31611042
31 + 31611011 = 31611042
131 + 31610911 = 31611042
149 + 31610893 = 31611042
251 + 31610791 = 31611042
263 + 31610779 = 31611042

Showing the first eight; more decompositions exist.
