Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612050, here are decompositions:

7 + 31612043 = 31612050
37 + 31612013 = 31612050
53 + 31611997 = 31612050
109 + 31611941 = 31612050
139 + 31611911 = 31612050
157 + 31611893 = 31612050
167 + 31611883 = 31612050
181 + 31611869 = 31612050

Showing the first eight; more decompositions exist.
