Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603458, here are decompositions:

31 + 31603427 = 31603458
97 + 31603361 = 31603458
149 + 31603309 = 31603458
197 + 31603261 = 31603458
199 + 31603259 = 31603458
311 + 31603147 = 31603458
317 + 31603141 = 31603458
347 + 31603111 = 31603458

Showing the first eight; more decompositions exist.
