Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514228, here are decompositions:

7 + 31514221 = 31514228
37 + 31514191 = 31514228
79 + 31514149 = 31514228
127 + 31514101 = 31514228
241 + 31513987 = 31514228
271 + 31513957 = 31514228
337 + 31513891 = 31514228
349 + 31513879 = 31514228

Showing the first eight; more decompositions exist.
