Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615038, here are decompositions:

31 + 31615007 = 31615038
97 + 31614941 = 31615038
109 + 31614929 = 31615038
139 + 31614899 = 31615038
149 + 31614889 = 31615038
157 + 31614881 = 31615038
179 + 31614859 = 31615038
199 + 31614839 = 31615038

Showing the first eight; more decompositions exist.
