Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523636, here are decompositions:

5 + 523631 = 523636
59 + 523577 = 523636
83 + 523553 = 523636
149 + 523487 = 523636
173 + 523463 = 523636
233 + 523403 = 523636
467 + 523169 = 523636
587 + 523049 = 523636

Showing the first eight; more decompositions exist.
