Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476078, here are decompositions:

5 + 31476073 = 31476078
19 + 31476059 = 31476078
47 + 31476031 = 31476078
61 + 31476017 = 31476078
149 + 31475929 = 31476078
167 + 31475911 = 31476078
229 + 31475849 = 31476078
251 + 31475827 = 31476078

Showing the first eight; more decompositions exist.
