Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479414, here are decompositions:

107 + 31479307 = 31479414
137 + 31479277 = 31479414
163 + 31479251 = 31479414
173 + 31479241 = 31479414
283 + 31479131 = 31479414
313 + 31479101 = 31479414
331 + 31479083 = 31479414
353 + 31479061 = 31479414

Showing the first eight; more decompositions exist.
