Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484222, here are decompositions:

13 + 31484209 = 31484222
19 + 31484203 = 31484222
43 + 31484179 = 31484222
61 + 31484161 = 31484222
79 + 31484143 = 31484222
151 + 31484071 = 31484222
163 + 31484059 = 31484222
241 + 31483981 = 31484222

Showing the first eight; more decompositions exist.
