Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604822, here are decompositions:

19 + 31604803 = 31604822
79 + 31604743 = 31604822
103 + 31604719 = 31604822
181 + 31604641 = 31604822
211 + 31604611 = 31604822
313 + 31604509 = 31604822
439 + 31604383 = 31604822
463 + 31604359 = 31604822

Showing the first eight; more decompositions exist.
