Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458476, here are decompositions:

73 + 31458403 = 31458476
97 + 31458379 = 31458476
103 + 31458373 = 31458476
199 + 31458277 = 31458476
307 + 31458169 = 31458476
463 + 31458013 = 31458476
487 + 31457989 = 31458476
547 + 31457929 = 31458476

Showing the first eight; more decompositions exist.
