Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31578096, here are decompositions:

5 + 31578091 = 31578096
29 + 31578067 = 31578096
73 + 31578023 = 31578096
157 + 31577939 = 31578096
167 + 31577929 = 31578096
197 + 31577899 = 31578096
283 + 31577813 = 31578096
313 + 31577783 = 31578096

Showing the first eight; more decompositions exist.
