Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603908, here are decompositions:

19 + 31603889 = 31603908
29 + 31603879 = 31603908
31 + 31603877 = 31603908
79 + 31603829 = 31603908
107 + 31603801 = 31603908
151 + 31603757 = 31603908
157 + 31603751 = 31603908
191 + 31603717 = 31603908

Showing the first eight; more decompositions exist.
