Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504324, here are decompositions:

191 + 31504133 = 31504324
197 + 31504127 = 31504324
227 + 31504097 = 31504324
311 + 31504013 = 31504324
347 + 31503977 = 31504324
353 + 31503971 = 31504324
461 + 31503863 = 31504324
881 + 31503443 = 31504324

Showing the first eight; more decompositions exist.
