Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479716, here are decompositions:

19 + 31479697 = 31479716
67 + 31479649 = 31479716
97 + 31479619 = 31479716
127 + 31479589 = 31479716
139 + 31479577 = 31479716
157 + 31479559 = 31479716
199 + 31479517 = 31479716
277 + 31479439 = 31479716

Showing the first eight; more decompositions exist.
