Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604168, here are decompositions:

31 + 31604137 = 31604168
181 + 31603987 = 31604168
367 + 31603801 = 31604168
457 + 31603711 = 31604168
487 + 31603681 = 31604168
601 + 31603567 = 31604168
787 + 31603381 = 31604168
859 + 31603309 = 31604168

Showing the first eight; more decompositions exist.
