Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102148, here are decompositions:

41 + 102107 = 102148
47 + 102101 = 102148
71 + 102077 = 102148
89 + 102059 = 102148
149 + 101999 = 102148
191 + 101957 = 102148
227 + 101921 = 102148
257 + 101891 = 102148

Showing the first eight; more decompositions exist.
