Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504276, here are decompositions:

47 + 31504229 = 31504276
149 + 31504127 = 31504276
173 + 31504103 = 31504276
179 + 31504097 = 31504276
239 + 31504037 = 31504276
263 + 31504013 = 31504276
347 + 31503929 = 31504276
359 + 31503917 = 31504276

Showing the first eight; more decompositions exist.
