Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603020, here are decompositions:

11 + 31603009 = 31603020
47 + 31602973 = 31603020
61 + 31602959 = 31603020
89 + 31602931 = 31603020
103 + 31602917 = 31603020
157 + 31602863 = 31603020
167 + 31602853 = 31603020
227 + 31602793 = 31603020

Showing the first eight; more decompositions exist.
