Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603582, here are decompositions:

5 + 31603577 = 31603582
29 + 31603553 = 31603582
71 + 31603511 = 31603582
239 + 31603343 = 31603582
389 + 31603193 = 31603582
443 + 31603139 = 31603582
503 + 31603079 = 31603582
509 + 31603073 = 31603582

Showing the first eight; more decompositions exist.
