Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446234, here are decompositions:

5 + 31446229 = 31446234
7 + 31446227 = 31446234
11 + 31446223 = 31446234
23 + 31446211 = 31446234
67 + 31446167 = 31446234
101 + 31446133 = 31446234
103 + 31446131 = 31446234
137 + 31446097 = 31446234

Showing the first eight; more decompositions exist.
