Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604222, here are decompositions:

3 + 31604219 = 31604222
31 + 31604191 = 31604222
379 + 31603843 = 31604222
421 + 31603801 = 31604222
541 + 31603681 = 31604222
613 + 31603609 = 31604222
733 + 31603489 = 31604222
829 + 31603393 = 31604222

Showing the first eight; more decompositions exist.
