Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514566, here are decompositions:

29 + 31514537 = 31514566
53 + 31514513 = 31514566
89 + 31514477 = 31514566
137 + 31514429 = 31514566
257 + 31514309 = 31514566
269 + 31514297 = 31514566
599 + 31513967 = 31514566
773 + 31513793 = 31514566

Showing the first eight; more decompositions exist.
