Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603038, here are decompositions:

11 + 31603027 = 31603038
29 + 31603009 = 31603038
79 + 31602959 = 31603038
107 + 31602931 = 31603038
139 + 31602899 = 31603038
179 + 31602859 = 31603038
347 + 31602691 = 31603038
349 + 31602689 = 31603038

Showing the first eight; more decompositions exist.
