Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603330, here are decompositions:

71 + 31603259 = 31603330
137 + 31603193 = 31603330
173 + 31603157 = 31603330
191 + 31603139 = 31603330
251 + 31603079 = 31603330
257 + 31603073 = 31603330
431 + 31602899 = 31603330
467 + 31602863 = 31603330

Showing the first eight; more decompositions exist.
