Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603372, here are decompositions:

5 + 31603367 = 31603372
11 + 31603361 = 31603372
29 + 31603343 = 31603372
113 + 31603259 = 31603372
179 + 31603193 = 31603372
233 + 31603139 = 31603372
263 + 31603109 = 31603372
293 + 31603079 = 31603372

Showing the first eight; more decompositions exist.
