Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603090, here are decompositions:

11 + 31603079 = 31603090
17 + 31603073 = 31603090
131 + 31602959 = 31603090
173 + 31602917 = 31603090
191 + 31602899 = 31603090
227 + 31602863 = 31603090
401 + 31602689 = 31603090
443 + 31602647 = 31603090

Showing the first eight; more decompositions exist.
