Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604834, here are decompositions:

31 + 31604803 = 31604834
67 + 31604767 = 31604834
103 + 31604731 = 31604834
193 + 31604641 = 31604834
223 + 31604611 = 31604834
277 + 31604557 = 31604834
337 + 31604497 = 31604834
463 + 31604371 = 31604834

Showing the first eight; more decompositions exist.
