Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603216, here are decompositions:

23 + 31603193 = 31603216
59 + 31603157 = 31603216
107 + 31603109 = 31603216
137 + 31603079 = 31603216
257 + 31602959 = 31603216
317 + 31602899 = 31603216
353 + 31602863 = 31603216
569 + 31602647 = 31603216

Showing the first eight; more decompositions exist.
