Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504422, here are decompositions:

71 + 31504351 = 31504422
193 + 31504229 = 31504422
233 + 31504189 = 31504422
239 + 31504183 = 31504422
293 + 31504129 = 31504422
409 + 31504013 = 31504422
449 + 31503973 = 31504422
461 + 31503961 = 31504422

Showing the first eight; more decompositions exist.
