Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445096, here are decompositions:

3 + 31445093 = 31445096
79 + 31445017 = 31445096
103 + 31444993 = 31445096
157 + 31444939 = 31445096
283 + 31444813 = 31445096
307 + 31444789 = 31445096
337 + 31444759 = 31445096
373 + 31444723 = 31445096

Showing the first eight; more decompositions exist.
