Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557096, here are decompositions:

19 + 31557077 = 31557096
73 + 31557023 = 31557096
83 + 31557013 = 31557096
89 + 31557007 = 31557096
139 + 31556957 = 31557096
157 + 31556939 = 31557096
173 + 31556923 = 31557096
227 + 31556869 = 31557096

Showing the first eight; more decompositions exist.
