Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603110, here are decompositions:

31 + 31603079 = 31603110
37 + 31603073 = 31603110
83 + 31603027 = 31603110
101 + 31603009 = 31603110
137 + 31602973 = 31603110
151 + 31602959 = 31603110
179 + 31602931 = 31603110
193 + 31602917 = 31603110

Showing the first eight; more decompositions exist.
