Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484086, here are decompositions:

5 + 31484081 = 31484086
17 + 31484069 = 31484086
107 + 31483979 = 31484086
167 + 31483919 = 31484086
173 + 31483913 = 31484086
197 + 31483889 = 31484086
353 + 31483733 = 31484086
503 + 31483583 = 31484086

Showing the first eight; more decompositions exist.
