Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484550, here are decompositions:

7 + 31484543 = 31484550
17 + 31484533 = 31484550
37 + 31484513 = 31484550
47 + 31484503 = 31484550
89 + 31484461 = 31484550
101 + 31484449 = 31484550
137 + 31484413 = 31484550
173 + 31484377 = 31484550

Showing the first eight; more decompositions exist.
