Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478422, here are decompositions:

11 + 31478411 = 31478422
23 + 31478399 = 31478422
29 + 31478393 = 31478422
71 + 31478351 = 31478422
89 + 31478333 = 31478422
113 + 31478309 = 31478422
233 + 31478189 = 31478422
251 + 31478171 = 31478422

Showing the first eight; more decompositions exist.
