Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603896, here are decompositions:

7 + 31603889 = 31603896
17 + 31603879 = 31603896
19 + 31603877 = 31603896
53 + 31603843 = 31603896
67 + 31603829 = 31603896
139 + 31603757 = 31603896
157 + 31603739 = 31603896
179 + 31603717 = 31603896

Showing the first eight; more decompositions exist.
