Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528752, here are decompositions:

43 + 528709 = 528752
61 + 528691 = 528752
73 + 528679 = 528752
79 + 528673 = 528752
193 + 528559 = 528752
241 + 528511 = 528752
283 + 528469 = 528752
349 + 528403 = 528752

Showing the first eight; more decompositions exist.
