Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603068, here are decompositions:

41 + 31603027 = 31603068
59 + 31603009 = 31603068
109 + 31602959 = 31603068
137 + 31602931 = 31603068
151 + 31602917 = 31603068
191 + 31602877 = 31603068
379 + 31602689 = 31603068
389 + 31602679 = 31603068

Showing the first eight; more decompositions exist.
