Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476950, here are decompositions:

3 + 31476947 = 31476950
19 + 31476931 = 31476950
79 + 31476871 = 31476950
97 + 31476853 = 31476950
103 + 31476847 = 31476950
151 + 31476799 = 31476950
223 + 31476727 = 31476950
433 + 31476517 = 31476950

Showing the first eight; more decompositions exist.
