Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521362, here are decompositions:

3 + 521359 = 521362
5 + 521357 = 521362
53 + 521309 = 521362
131 + 521231 = 521362
311 + 521051 = 521362
353 + 521009 = 521362
419 + 520943 = 521362
449 + 520913 = 521362

Showing the first eight; more decompositions exist.
