Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102774, here are decompositions:

5 + 102769 = 102774
11 + 102763 = 102774
13 + 102761 = 102774
73 + 102701 = 102774
97 + 102677 = 102774
101 + 102673 = 102774
107 + 102667 = 102774
127 + 102647 = 102774

Showing the first eight; more decompositions exist.
