Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484418, here are decompositions:

5 + 31484413 = 31484418
41 + 31484377 = 31484418
59 + 31484359 = 31484418
79 + 31484339 = 31484418
101 + 31484317 = 31484418
137 + 31484281 = 31484418
151 + 31484267 = 31484418
179 + 31484239 = 31484418

Showing the first eight; more decompositions exist.
