Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504664, here are decompositions:

3 + 31504661 = 31504664
13 + 31504651 = 31504664
73 + 31504591 = 31504664
97 + 31504567 = 31504664
211 + 31504453 = 31504664
277 + 31504387 = 31504664
307 + 31504357 = 31504664
313 + 31504351 = 31504664

Showing the first eight; more decompositions exist.
