Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446156, here are decompositions:

23 + 31446133 = 31446156
59 + 31446097 = 31446156
89 + 31446067 = 31446156
103 + 31446053 = 31446156
173 + 31445983 = 31446156
179 + 31445977 = 31446156
197 + 31445959 = 31446156
199 + 31445957 = 31446156

Showing the first eight; more decompositions exist.
