Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476508, here are decompositions:

47 + 31476461 = 31476508
59 + 31476449 = 31476508
71 + 31476437 = 31476508
137 + 31476371 = 31476508
191 + 31476317 = 31476508
257 + 31476251 = 31476508
269 + 31476239 = 31476508
359 + 31476149 = 31476508

Showing the first eight; more decompositions exist.
