Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603564, here are decompositions:

11 + 31603553 = 31603564
53 + 31603511 = 31603564
137 + 31603427 = 31603564
197 + 31603367 = 31603564
491 + 31603073 = 31603564
647 + 31602917 = 31603564
701 + 31602863 = 31603564
761 + 31602803 = 31603564

Showing the first eight; more decompositions exist.
