Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504026, here are decompositions:

13 + 31504013 = 31504026
53 + 31503973 = 31504026
97 + 31503929 = 31504026
109 + 31503917 = 31504026
139 + 31503887 = 31504026
163 + 31503863 = 31504026
173 + 31503853 = 31504026
179 + 31503847 = 31504026

Showing the first eight; more decompositions exist.
