Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468050, here are decompositions:

23 + 31468027 = 31468050
37 + 31468013 = 31468050
67 + 31467983 = 31468050
83 + 31467967 = 31468050
101 + 31467949 = 31468050
113 + 31467937 = 31468050
139 + 31467911 = 31468050
151 + 31467899 = 31468050

Showing the first eight; more decompositions exist.
