Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504108, here are decompositions:

5 + 31504103 = 31504108
11 + 31504097 = 31504108
71 + 31504037 = 31504108
131 + 31503977 = 31504108
137 + 31503971 = 31504108
179 + 31503929 = 31504108
191 + 31503917 = 31504108
197 + 31503911 = 31504108

Showing the first eight; more decompositions exist.
