Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521382, here are decompositions:

5 + 521377 = 521382
13 + 521369 = 521382
19 + 521363 = 521382
23 + 521359 = 521382
53 + 521329 = 521382
73 + 521309 = 521382
83 + 521299 = 521382
101 + 521281 = 521382

Showing the first eight; more decompositions exist.
