Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603466, here are decompositions:

73 + 31603393 = 31603466
157 + 31603309 = 31603466
439 + 31603027 = 31603466
457 + 31603009 = 31603466
607 + 31602859 = 31603466
613 + 31602853 = 31603466
673 + 31602793 = 31603466
787 + 31602679 = 31603466

Showing the first eight; more decompositions exist.
