Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478476, here are decompositions:

5 + 31478471 = 31478476
47 + 31478429 = 31478476
83 + 31478393 = 31478476
149 + 31478327 = 31478476
167 + 31478309 = 31478476
347 + 31478129 = 31478476
509 + 31477967 = 31478476
569 + 31477907 = 31478476

Showing the first eight; more decompositions exist.
