Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603080, here are decompositions:

7 + 31603073 = 31603080
53 + 31603027 = 31603080
71 + 31603009 = 31603080
107 + 31602973 = 31603080
149 + 31602931 = 31603080
163 + 31602917 = 31603080
181 + 31602899 = 31603080
227 + 31602853 = 31603080

Showing the first eight; more decompositions exist.
