Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482270, here are decompositions:

13 + 31482257 = 31482270
23 + 31482247 = 31482270
41 + 31482229 = 31482270
97 + 31482173 = 31482270
101 + 31482169 = 31482270
103 + 31482167 = 31482270
151 + 31482119 = 31482270
167 + 31482103 = 31482270

Showing the first eight; more decompositions exist.
