Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603086, here are decompositions:

7 + 31603079 = 31603086
13 + 31603073 = 31603086
59 + 31603027 = 31603086
113 + 31602973 = 31603086
127 + 31602959 = 31603086
223 + 31602863 = 31603086
227 + 31602859 = 31603086
233 + 31602853 = 31603086

Showing the first eight; more decompositions exist.
