Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504946, here are decompositions:

3 + 31504943 = 31504946
37 + 31504909 = 31504946
43 + 31504903 = 31504946
73 + 31504873 = 31504946
127 + 31504819 = 31504946
163 + 31504783 = 31504946
199 + 31504747 = 31504946
373 + 31504573 = 31504946

Showing the first eight; more decompositions exist.
