Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476458, here are decompositions:

7 + 31476451 = 31476458
67 + 31476391 = 31476458
109 + 31476349 = 31476458
271 + 31476187 = 31476458
547 + 31475911 = 31476458
631 + 31475827 = 31476458
661 + 31475797 = 31476458
709 + 31475749 = 31476458

Showing the first eight; more decompositions exist.
