Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482222, here are decompositions:

43 + 31482179 = 31482222
53 + 31482169 = 31482222
103 + 31482119 = 31482222
139 + 31482083 = 31482222
179 + 31482043 = 31482222
181 + 31482041 = 31482222
241 + 31481981 = 31482222
271 + 31481951 = 31482222

Showing the first eight; more decompositions exist.
