Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476528, here are decompositions:

11 + 31476517 = 31476528
19 + 31476509 = 31476528
29 + 31476499 = 31476528
67 + 31476461 = 31476528
71 + 31476457 = 31476528
79 + 31476449 = 31476528
137 + 31476391 = 31476528
157 + 31476371 = 31476528

Showing the first eight; more decompositions exist.
