Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504264, here are decompositions:

131 + 31504133 = 31504264
137 + 31504127 = 31504264
167 + 31504097 = 31504264
227 + 31504037 = 31504264
251 + 31504013 = 31504264
293 + 31503971 = 31504264
347 + 31503917 = 31504264
353 + 31503911 = 31504264

Showing the first eight; more decompositions exist.
