Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610082, here are decompositions:

19 + 31610063 = 31610082
43 + 31610039 = 31610082
59 + 31610023 = 31610082
71 + 31610011 = 31610082
73 + 31610009 = 31610082
89 + 31609993 = 31610082
109 + 31609973 = 31610082
149 + 31609933 = 31610082

Showing the first eight; more decompositions exist.
