Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476038, here are decompositions:

7 + 31476031 = 31476038
109 + 31475929 = 31476038
127 + 31475911 = 31476038
211 + 31475827 = 31476038
241 + 31475797 = 31476038
439 + 31475599 = 31476038
457 + 31475581 = 31476038
547 + 31475491 = 31476038

Showing the first eight; more decompositions exist.
