Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603648, here are decompositions:

5 + 31603643 = 31603648
71 + 31603577 = 31603648
137 + 31603511 = 31603648
281 + 31603367 = 31603648
389 + 31603259 = 31603648
491 + 31603157 = 31603648
509 + 31603139 = 31603648
569 + 31603079 = 31603648

Showing the first eight; more decompositions exist.
