Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484212, here are decompositions:

3 + 31484209 = 31484212
5 + 31484207 = 31484212
83 + 31484129 = 31484212
131 + 31484081 = 31484212
233 + 31483979 = 31484212
293 + 31483919 = 31484212
479 + 31483733 = 31484212
521 + 31483691 = 31484212

Showing the first eight; more decompositions exist.
