Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528050, here are decompositions:

13 + 31528037 = 31528050
31 + 31528019 = 31528050
53 + 31527997 = 31528050
83 + 31527967 = 31528050
109 + 31527941 = 31528050
137 + 31527913 = 31528050
163 + 31527887 = 31528050
223 + 31527827 = 31528050

Showing the first eight; more decompositions exist.
