Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479348, here are decompositions:

11 + 31479337 = 31479348
41 + 31479307 = 31479348
59 + 31479289 = 31479348
71 + 31479277 = 31479348
79 + 31479269 = 31479348
97 + 31479251 = 31479348
107 + 31479241 = 31479348
151 + 31479197 = 31479348

Showing the first eight; more decompositions exist.
