Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130752, here are decompositions:

23 + 130729 = 130752
53 + 130699 = 130752
59 + 130693 = 130752
71 + 130681 = 130752
101 + 130651 = 130752
103 + 130649 = 130752
109 + 130643 = 130752
113 + 130639 = 130752

Showing the first eight; more decompositions exist.
