Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603416, here are decompositions:

23 + 31603393 = 31603416
73 + 31603343 = 31603416
107 + 31603309 = 31603416
157 + 31603259 = 31603416
167 + 31603249 = 31603416
223 + 31603193 = 31603416
269 + 31603147 = 31603416
277 + 31603139 = 31603416

Showing the first eight; more decompositions exist.
