Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603132, here are decompositions:

23 + 31603109 = 31603132
53 + 31603079 = 31603132
59 + 31603073 = 31603132
173 + 31602959 = 31603132
233 + 31602899 = 31603132
269 + 31602863 = 31603132
443 + 31602689 = 31603132
593 + 31602539 = 31603132

Showing the first eight; more decompositions exist.
