Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603332, here are decompositions:

23 + 31603309 = 31603332
71 + 31603261 = 31603332
73 + 31603259 = 31603332
83 + 31603249 = 31603332
139 + 31603193 = 31603332
191 + 31603141 = 31603332
193 + 31603139 = 31603332
223 + 31603109 = 31603332

Showing the first eight; more decompositions exist.
