Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610052, here are decompositions:

13 + 31610039 = 31610052
29 + 31610023 = 31610052
41 + 31610011 = 31610052
43 + 31610009 = 31610052
59 + 31609993 = 31610052
79 + 31609973 = 31610052
181 + 31609871 = 31610052
191 + 31609861 = 31610052

Showing the first eight; more decompositions exist.
