Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479476, here are decompositions:

19 + 31479457 = 31479476
37 + 31479439 = 31479476
139 + 31479337 = 31479476
199 + 31479277 = 31479476
349 + 31479127 = 31479476
739 + 31478737 = 31479476
757 + 31478719 = 31479476
829 + 31478647 = 31479476

Showing the first eight; more decompositions exist.
