Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476994, here are decompositions:

47 + 31476947 = 31476994
113 + 31476881 = 31476994
173 + 31476821 = 31476994
251 + 31476743 = 31476994
383 + 31476611 = 31476994
401 + 31476593 = 31476994
443 + 31476551 = 31476994
557 + 31476437 = 31476994

Showing the first eight; more decompositions exist.
