Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450086, here are decompositions:

29 + 31450057 = 31450086
43 + 31450043 = 31450086
53 + 31450033 = 31450086
97 + 31449989 = 31450086
149 + 31449937 = 31450086
163 + 31449923 = 31450086
233 + 31449853 = 31450086
263 + 31449823 = 31450086

Showing the first eight; more decompositions exist.
