Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603432, here are decompositions:

5 + 31603427 = 31603432
71 + 31603361 = 31603432
89 + 31603343 = 31603432
173 + 31603259 = 31603432
239 + 31603193 = 31603432
293 + 31603139 = 31603432
353 + 31603079 = 31603432
359 + 31603073 = 31603432

Showing the first eight; more decompositions exist.
