Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479274, here are decompositions:

3 + 31479271 = 31479274
5 + 31479269 = 31479274
23 + 31479251 = 31479274
173 + 31479101 = 31479274
191 + 31479083 = 31479274
257 + 31479017 = 31479274
317 + 31478957 = 31479274
443 + 31478831 = 31479274

Showing the first eight; more decompositions exist.
