Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511346, here are decompositions:

5 + 31511341 = 31511346
19 + 31511327 = 31511346
59 + 31511287 = 31511346
157 + 31511189 = 31511346
179 + 31511167 = 31511346
199 + 31511147 = 31511346
257 + 31511089 = 31511346
277 + 31511069 = 31511346

Showing the first eight; more decompositions exist.
