Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603446, here are decompositions:

19 + 31603427 = 31603446
53 + 31603393 = 31603446
79 + 31603367 = 31603446
103 + 31603343 = 31603446
137 + 31603309 = 31603446
197 + 31603249 = 31603446
307 + 31603139 = 31603446
337 + 31603109 = 31603446

Showing the first eight; more decompositions exist.
