Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603622, here are decompositions:

13 + 31603609 = 31603622
103 + 31603519 = 31603622
229 + 31603393 = 31603622
241 + 31603381 = 31603622
313 + 31603309 = 31603622
373 + 31603249 = 31603622
499 + 31603123 = 31603622
613 + 31603009 = 31603622

Showing the first eight; more decompositions exist.
