Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102150, here are decompositions:

11 + 102139 = 102150
29 + 102121 = 102150
43 + 102107 = 102150
47 + 102103 = 102150
71 + 102079 = 102150
73 + 102077 = 102150
79 + 102071 = 102150
89 + 102061 = 102150

Showing the first eight; more decompositions exist.
