Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604576, here are decompositions:

19 + 31604557 = 31604576
43 + 31604533 = 31604576
67 + 31604509 = 31604576
79 + 31604497 = 31604576
193 + 31604383 = 31604576
229 + 31604347 = 31604576
277 + 31604299 = 31604576
313 + 31604263 = 31604576

Showing the first eight; more decompositions exist.
