Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102072, here are decompositions:

11 + 102061 = 102072
13 + 102059 = 102072
29 + 102043 = 102072
41 + 102031 = 102072
53 + 102019 = 102072
59 + 102013 = 102072
71 + 102001 = 102072
73 + 101999 = 102072

Showing the first eight; more decompositions exist.
