Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522086, here are decompositions:

67 + 31522019 = 31522086
73 + 31522013 = 31522086
107 + 31521979 = 31522086
109 + 31521977 = 31522086
199 + 31521887 = 31522086
223 + 31521863 = 31522086
257 + 31521829 = 31522086
293 + 31521793 = 31522086

Showing the first eight; more decompositions exist.
