Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484510, here are decompositions:

7 + 31484503 = 31484510
61 + 31484449 = 31484510
97 + 31484413 = 31484510
151 + 31484359 = 31484510
157 + 31484353 = 31484510
193 + 31484317 = 31484510
229 + 31484281 = 31484510
271 + 31484239 = 31484510

Showing the first eight; more decompositions exist.
