Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504126, here are decompositions:

23 + 31504103 = 31504126
29 + 31504097 = 31504126
89 + 31504037 = 31504126
113 + 31504013 = 31504126
149 + 31503977 = 31504126
197 + 31503929 = 31504126
239 + 31503887 = 31504126
263 + 31503863 = 31504126

Showing the first eight; more decompositions exist.
