Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102756, here are decompositions:

79 + 102677 = 102756
83 + 102673 = 102756
89 + 102667 = 102756
103 + 102653 = 102756
109 + 102647 = 102756
113 + 102643 = 102756
149 + 102607 = 102756
163 + 102593 = 102756

Showing the first eight; more decompositions exist.
