Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615050, here are decompositions:

11 + 31615039 = 31615050
37 + 31615013 = 31615050
43 + 31615007 = 31615050
97 + 31614953 = 31615050
107 + 31614943 = 31615050
109 + 31614941 = 31615050
151 + 31614899 = 31615050
191 + 31614859 = 31615050

Showing the first eight; more decompositions exist.
