Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482282, here are decompositions:

5 + 31482277 = 31482282
11 + 31482271 = 31482282
53 + 31482229 = 31482282
103 + 31482179 = 31482282
109 + 31482173 = 31482282
113 + 31482169 = 31482282
163 + 31482119 = 31482282
179 + 31482103 = 31482282

Showing the first eight; more decompositions exist.
