Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484576, here are decompositions:

7 + 31484569 = 31484576
43 + 31484533 = 31484576
73 + 31484503 = 31484576
127 + 31484449 = 31484576
163 + 31484413 = 31484576
199 + 31484377 = 31484576
223 + 31484353 = 31484576
337 + 31484239 = 31484576

Showing the first eight; more decompositions exist.
