Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521752, here are decompositions:

3 + 521749 = 521752
29 + 521723 = 521752
59 + 521693 = 521752
83 + 521669 = 521752
149 + 521603 = 521752
233 + 521519 = 521752
269 + 521483 = 521752
281 + 521471 = 521752

Showing the first eight; more decompositions exist.
