Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479344, here are decompositions:

7 + 31479337 = 31479344
37 + 31479307 = 31479344
67 + 31479277 = 31479344
73 + 31479271 = 31479344
103 + 31479241 = 31479344
271 + 31479073 = 31479344
283 + 31479061 = 31479344
313 + 31479031 = 31479344

Showing the first eight; more decompositions exist.
