Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523684, here are decompositions:

3 + 523681 = 523684
11 + 523673 = 523684
17 + 523667 = 523684
47 + 523637 = 523684
53 + 523631 = 523684
107 + 523577 = 523684
113 + 523571 = 523684
131 + 523553 = 523684

Showing the first eight; more decompositions exist.
