Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78552, here are decompositions:

11 + 78541 = 78552
13 + 78539 = 78552
41 + 78511 = 78552
43 + 78509 = 78552
73 + 78479 = 78552
113 + 78439 = 78552
151 + 78401 = 78552
211 + 78341 = 78552

Showing the first eight; more decompositions exist.
