Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603616, here are decompositions:

3 + 31603613 = 31603616
7 + 31603609 = 31603616
97 + 31603519 = 31603616
127 + 31603489 = 31603616
223 + 31603393 = 31603616
307 + 31603309 = 31603616
367 + 31603249 = 31603616
607 + 31603009 = 31603616

Showing the first eight; more decompositions exist.
