Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603456, here are decompositions:

29 + 31603427 = 31603456
89 + 31603367 = 31603456
113 + 31603343 = 31603456
197 + 31603259 = 31603456
263 + 31603193 = 31603456
317 + 31603139 = 31603456
347 + 31603109 = 31603456
383 + 31603073 = 31603456

Showing the first eight; more decompositions exist.
