Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603252, here are decompositions:

3 + 31603249 = 31603252
59 + 31603193 = 31603252
113 + 31603139 = 31603252
173 + 31603079 = 31603252
179 + 31603073 = 31603252
293 + 31602959 = 31603252
353 + 31602899 = 31603252
389 + 31602863 = 31603252

Showing the first eight; more decompositions exist.
