Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504064, here are decompositions:

13 + 31504051 = 31504064
103 + 31503961 = 31504064
181 + 31503883 = 31504064
211 + 31503853 = 31504064
223 + 31503841 = 31504064
313 + 31503751 = 31504064
331 + 31503733 = 31504064
337 + 31503727 = 31504064

Showing the first eight; more decompositions exist.
