Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446258, here are decompositions:

5 + 31446253 = 31446258
7 + 31446251 = 31446258
17 + 31446241 = 31446258
29 + 31446229 = 31446258
31 + 31446227 = 31446258
47 + 31446211 = 31446258
127 + 31446131 = 31446258
157 + 31446101 = 31446258

Showing the first eight; more decompositions exist.
