Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484518, here are decompositions:

5 + 31484513 = 31484518
101 + 31484417 = 31484518
179 + 31484339 = 31484518
251 + 31484267 = 31484518
281 + 31484237 = 31484518
311 + 31484207 = 31484518
389 + 31484129 = 31484518
449 + 31484069 = 31484518

Showing the first eight; more decompositions exist.
