Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445196, here are decompositions:

23 + 31445173 = 31445196
37 + 31445159 = 31445196
59 + 31445137 = 31445196
89 + 31445107 = 31445196
103 + 31445093 = 31445196
163 + 31445033 = 31445196
179 + 31445017 = 31445196
257 + 31444939 = 31445196

Showing the first eight; more decompositions exist.
