Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604876, here are decompositions:

13 + 31604863 = 31604876
73 + 31604803 = 31604876
109 + 31604767 = 31604876
157 + 31604719 = 31604876
229 + 31604647 = 31604876
367 + 31604509 = 31604876
379 + 31604497 = 31604876
577 + 31604299 = 31604876

Showing the first eight; more decompositions exist.
