Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610044, here are decompositions:

5 + 31610039 = 31610044
71 + 31609973 = 31610044
107 + 31609937 = 31610044
113 + 31609931 = 31610044
173 + 31609871 = 31610044
197 + 31609847 = 31610044
251 + 31609793 = 31610044
353 + 31609691 = 31610044

Showing the first eight; more decompositions exist.
