Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479294, here are decompositions:

5 + 31479289 = 31479294
17 + 31479277 = 31479294
23 + 31479271 = 31479294
43 + 31479251 = 31479294
53 + 31479241 = 31479294
97 + 31479197 = 31479294
163 + 31479131 = 31479294
167 + 31479127 = 31479294

Showing the first eight; more decompositions exist.
