Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603144, here are decompositions:

3 + 31603141 = 31603144
5 + 31603139 = 31603144
71 + 31603073 = 31603144
227 + 31602917 = 31603144
281 + 31602863 = 31603144
557 + 31602587 = 31603144
563 + 31602581 = 31603144
647 + 31602497 = 31603144

Showing the first eight; more decompositions exist.
