Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521876, here are decompositions:

7 + 521869 = 521876
67 + 521809 = 521876
109 + 521767 = 521876
127 + 521749 = 521876
337 + 521539 = 521876
349 + 521527 = 521876
373 + 521503 = 521876
379 + 521497 = 521876

Showing the first eight; more decompositions exist.
