Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603992, here are decompositions:

5 + 31603987 = 31603992
59 + 31603933 = 31603992
61 + 31603931 = 31603992
73 + 31603919 = 31603992
103 + 31603889 = 31603992
113 + 31603879 = 31603992
149 + 31603843 = 31603992
163 + 31603829 = 31603992

Showing the first eight; more decompositions exist.
