Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603204, here are decompositions:

11 + 31603193 = 31603204
47 + 31603157 = 31603204
131 + 31603073 = 31603204
401 + 31602803 = 31603204
557 + 31602647 = 31603204
617 + 31602587 = 31603204
683 + 31602521 = 31603204
761 + 31602443 = 31603204

Showing the first eight; more decompositions exist.
