Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102724, here are decompositions:

23 + 102701 = 102724
47 + 102677 = 102724
71 + 102653 = 102724
113 + 102611 = 102724
131 + 102593 = 102724
137 + 102587 = 102724
173 + 102551 = 102724
191 + 102533 = 102724

Showing the first eight; more decompositions exist.
