Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504222, here are decompositions:

3 + 31504219 = 31504222
89 + 31504133 = 31504222
251 + 31503971 = 31504222
293 + 31503929 = 31504222
311 + 31503911 = 31504222
359 + 31503863 = 31504222
443 + 31503779 = 31504222
509 + 31503713 = 31504222

Showing the first eight; more decompositions exist.
