Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102180, here are decompositions:

19 + 102161 = 102180
31 + 102149 = 102180
41 + 102139 = 102180
59 + 102121 = 102180
73 + 102107 = 102180
79 + 102101 = 102180
101 + 102079 = 102180
103 + 102077 = 102180

Showing the first eight; more decompositions exist.
