Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521526, here are decompositions:

7 + 521519 = 521526
23 + 521503 = 521526
29 + 521497 = 521526
43 + 521483 = 521526
79 + 521447 = 521526
97 + 521429 = 521526
127 + 521399 = 521526
149 + 521377 = 521526

Showing the first eight; more decompositions exist.
