Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603630, here are decompositions:

17 + 31603613 = 31603630
53 + 31603577 = 31603630
263 + 31603367 = 31603630
269 + 31603361 = 31603630
491 + 31603139 = 31603630
521 + 31603109 = 31603630
557 + 31603073 = 31603630
827 + 31602803 = 31603630

Showing the first eight; more decompositions exist.
