Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514476, here are decompositions:

3 + 31514473 = 31514476
47 + 31514429 = 31514476
53 + 31514423 = 31514476
167 + 31514309 = 31514476
179 + 31514297 = 31514476
317 + 31514159 = 31514476
509 + 31513967 = 31514476
599 + 31513877 = 31514476

Showing the first eight; more decompositions exist.
