Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603542, here are decompositions:

23 + 31603519 = 31603542
31 + 31603511 = 31603542
53 + 31603489 = 31603542
149 + 31603393 = 31603542
181 + 31603361 = 31603542
199 + 31603343 = 31603542
233 + 31603309 = 31603542
281 + 31603261 = 31603542

Showing the first eight; more decompositions exist.
