Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504306, here are decompositions:

3 + 31504303 = 31504306
173 + 31504133 = 31504306
179 + 31504127 = 31504306
269 + 31504037 = 31504306
293 + 31504013 = 31504306
389 + 31503917 = 31504306
419 + 31503887 = 31504306
443 + 31503863 = 31504306

Showing the first eight; more decompositions exist.
