Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603126, here are decompositions:

3 + 31603123 = 31603126
17 + 31603109 = 31603126
47 + 31603079 = 31603126
53 + 31603073 = 31603126
167 + 31602959 = 31603126
227 + 31602899 = 31603126
263 + 31602863 = 31603126
479 + 31602647 = 31603126

Showing the first eight; more decompositions exist.
