Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521762, here are decompositions:

13 + 521749 = 521762
19 + 521743 = 521762
103 + 521659 = 521762
181 + 521581 = 521762
211 + 521551 = 521762
223 + 521539 = 521762
229 + 521533 = 521762
271 + 521491 = 521762

Showing the first eight; more decompositions exist.
