Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484508, here are decompositions:

5 + 31484503 = 31484508
47 + 31484461 = 31484508
59 + 31484449 = 31484508
131 + 31484377 = 31484508
149 + 31484359 = 31484508
191 + 31484317 = 31484508
227 + 31484281 = 31484508
241 + 31484267 = 31484508

Showing the first eight; more decompositions exist.
