Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603032, here are decompositions:

5 + 31603027 = 31603032
23 + 31603009 = 31603032
59 + 31602973 = 31603032
73 + 31602959 = 31603032
101 + 31602931 = 31603032
173 + 31602859 = 31603032
179 + 31602853 = 31603032
229 + 31602803 = 31603032

Showing the first eight; more decompositions exist.
