Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504338, here are decompositions:

11 + 31504327 = 31504338
109 + 31504229 = 31504338
137 + 31504201 = 31504338
149 + 31504189 = 31504338
211 + 31504127 = 31504338
241 + 31504097 = 31504338
251 + 31504087 = 31504338
367 + 31503971 = 31504338

Showing the first eight; more decompositions exist.
