Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521376, here are decompositions:

7 + 521369 = 521376
13 + 521363 = 521376
17 + 521359 = 521376
19 + 521357 = 521376
47 + 521329 = 521376
59 + 521317 = 521376
67 + 521309 = 521376
109 + 521267 = 521376

Showing the first eight; more decompositions exist.
