Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604896, here are decompositions:

47 + 31604849 = 31604896
107 + 31604789 = 31604896
137 + 31604759 = 31604896
149 + 31604747 = 31604896
173 + 31604723 = 31604896
269 + 31604627 = 31604896
293 + 31604603 = 31604896
443 + 31604453 = 31604896

Showing the first eight; more decompositions exist.
