Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603936, here are decompositions:

3 + 31603933 = 31603936
5 + 31603931 = 31603936
17 + 31603919 = 31603936
47 + 31603889 = 31603936
59 + 31603877 = 31603936
107 + 31603829 = 31603936
179 + 31603757 = 31603936
197 + 31603739 = 31603936

Showing the first eight; more decompositions exist.
