Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610942, here are decompositions:

31 + 31610911 = 31610942
151 + 31610791 = 31610942
163 + 31610779 = 31610942
313 + 31610629 = 31610942
373 + 31610569 = 31610942
379 + 31610563 = 31610942
421 + 31610521 = 31610942
439 + 31610503 = 31610942

Showing the first eight; more decompositions exist.
