Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603716, here are decompositions:

5 + 31603711 = 31603716
7 + 31603709 = 31603716
59 + 31603657 = 31603716
73 + 31603643 = 31603716
103 + 31603613 = 31603716
107 + 31603609 = 31603716
139 + 31603577 = 31603716
149 + 31603567 = 31603716

Showing the first eight; more decompositions exist.
