Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742752, here are decompositions:

13 + 8742739 = 8742752
79 + 8742673 = 8742752
181 + 8742571 = 8742752
211 + 8742541 = 8742752
223 + 8742529 = 8742752
241 + 8742511 = 8742752
283 + 8742469 = 8742752
331 + 8742421 = 8742752

Showing the first eight; more decompositions exist.
