Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610068, here are decompositions:

5 + 31610063 = 31610068
29 + 31610039 = 31610068
59 + 31610009 = 31610068
101 + 31609967 = 31610068
131 + 31609937 = 31610068
137 + 31609931 = 31610068
197 + 31609871 = 31610068
389 + 31609679 = 31610068

Showing the first eight; more decompositions exist.
