Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504050, here are decompositions:

13 + 31504037 = 31504050
37 + 31504013 = 31504050
73 + 31503977 = 31504050
79 + 31503971 = 31504050
89 + 31503961 = 31504050
139 + 31503911 = 31504050
163 + 31503887 = 31504050
167 + 31503883 = 31504050

Showing the first eight; more decompositions exist.
