Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478334, here are decompositions:

7 + 31478327 = 31478334
11 + 31478323 = 31478334
47 + 31478287 = 31478334
67 + 31478267 = 31478334
163 + 31478171 = 31478334
257 + 31478077 = 31478334
311 + 31478023 = 31478334
317 + 31478017 = 31478334

Showing the first eight; more decompositions exist.
