Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603636, here are decompositions:

23 + 31603613 = 31603636
59 + 31603577 = 31603636
83 + 31603553 = 31603636
149 + 31603487 = 31603636
269 + 31603367 = 31603636
293 + 31603343 = 31603636
443 + 31603193 = 31603636
479 + 31603157 = 31603636

Showing the first eight; more decompositions exist.
