Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603116, here are decompositions:

5 + 31603111 = 31603116
7 + 31603109 = 31603116
37 + 31603079 = 31603116
43 + 31603073 = 31603116
89 + 31603027 = 31603116
107 + 31603009 = 31603116
157 + 31602959 = 31603116
199 + 31602917 = 31603116

Showing the first eight; more decompositions exist.
