Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603522, here are decompositions:

3 + 31603519 = 31603522
11 + 31603511 = 31603522
179 + 31603343 = 31603522
263 + 31603259 = 31603522
383 + 31603139 = 31603522
443 + 31603079 = 31603522
449 + 31603073 = 31603522
563 + 31602959 = 31603522

Showing the first eight; more decompositions exist.
