Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102744, here are decompositions:

43 + 102701 = 102744
67 + 102677 = 102744
71 + 102673 = 102744
97 + 102647 = 102744
101 + 102643 = 102744
137 + 102607 = 102744
151 + 102593 = 102744
157 + 102587 = 102744

Showing the first eight; more decompositions exist.
