Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521696, here are decompositions:

3 + 521693 = 521696
37 + 521659 = 521696
139 + 521557 = 521696
157 + 521539 = 521696
163 + 521533 = 521696
193 + 521503 = 521696
199 + 521497 = 521696
337 + 521359 = 521696

Showing the first eight; more decompositions exist.
