Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504066, here are decompositions:

29 + 31504037 = 31504066
53 + 31504013 = 31504066
89 + 31503977 = 31504066
137 + 31503929 = 31504066
149 + 31503917 = 31504066
179 + 31503887 = 31504066
257 + 31503809 = 31504066
317 + 31503749 = 31504066

Showing the first eight; more decompositions exist.
