Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 752, here are decompositions:

13 + 739 = 752
19 + 733 = 752
43 + 709 = 752
61 + 691 = 752
79 + 673 = 752
109 + 643 = 752
139 + 613 = 752
151 + 601 = 752

Showing the first eight; more decompositions exist.
