Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603338, here are decompositions:

29 + 31603309 = 31603338
79 + 31603259 = 31603338
89 + 31603249 = 31603338
181 + 31603157 = 31603338
191 + 31603147 = 31603338
197 + 31603141 = 31603338
199 + 31603139 = 31603338
227 + 31603111 = 31603338

Showing the first eight; more decompositions exist.
