Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484362, here are decompositions:

3 + 31484359 = 31484362
23 + 31484339 = 31484362
59 + 31484303 = 31484362
233 + 31484129 = 31484362
269 + 31484093 = 31484362
281 + 31484081 = 31484362
293 + 31484069 = 31484362
383 + 31483979 = 31484362

Showing the first eight; more decompositions exist.
