Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514428, here are decompositions:

5 + 31514423 = 31514428
131 + 31514297 = 31514428
137 + 31514291 = 31514428
167 + 31514261 = 31514428
269 + 31514159 = 31514428
347 + 31514081 = 31514428
461 + 31513967 = 31514428
641 + 31513787 = 31514428

Showing the first eight; more decompositions exist.
