Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604676, here are decompositions:

29 + 31604647 = 31604676
67 + 31604609 = 31604676
73 + 31604603 = 31604676
167 + 31604509 = 31604676
179 + 31604497 = 31604676
223 + 31604453 = 31604676
293 + 31604383 = 31604676
317 + 31604359 = 31604676

Showing the first eight; more decompositions exist.
