Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102130, here are decompositions:

23 + 102107 = 102130
29 + 102101 = 102130
53 + 102077 = 102130
59 + 102071 = 102130
71 + 102059 = 102130
107 + 102023 = 102130
131 + 101999 = 102130
167 + 101963 = 102130

Showing the first eight; more decompositions exist.
