Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603444, here are decompositions:

17 + 31603427 = 31603444
83 + 31603361 = 31603444
101 + 31603343 = 31603444
251 + 31603193 = 31603444
641 + 31602803 = 31603444
797 + 31602647 = 31603444
857 + 31602587 = 31603444
863 + 31602581 = 31603444

Showing the first eight; more decompositions exist.
