Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514070, here are decompositions:

11 + 31514059 = 31514070
47 + 31514023 = 31514070
83 + 31513987 = 31514070
103 + 31513967 = 31514070
113 + 31513957 = 31514070
127 + 31513943 = 31514070
179 + 31513891 = 31514070
191 + 31513879 = 31514070

Showing the first eight; more decompositions exist.
