Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576086, here are decompositions:

19 + 31576067 = 31576086
37 + 31576049 = 31576086
79 + 31576007 = 31576086
83 + 31576003 = 31576086
149 + 31575937 = 31576086
163 + 31575923 = 31576086
193 + 31575893 = 31576086
257 + 31575829 = 31576086

Showing the first eight; more decompositions exist.
