Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504084, here are decompositions:

47 + 31504037 = 31504084
71 + 31504013 = 31504084
107 + 31503977 = 31504084
113 + 31503971 = 31504084
167 + 31503917 = 31504084
173 + 31503911 = 31504084
197 + 31503887 = 31504084
641 + 31503443 = 31504084

Showing the first eight; more decompositions exist.
