Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514162, here are decompositions:

3 + 31514159 = 31514162
13 + 31514149 = 31514162
19 + 31514143 = 31514162
61 + 31514101 = 31514162
103 + 31514059 = 31514162
139 + 31514023 = 31514162
271 + 31513891 = 31514162
283 + 31513879 = 31514162

Showing the first eight; more decompositions exist.
