Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68130, here are decompositions:

17 + 68113 = 68130
19 + 68111 = 68130
31 + 68099 = 68130
43 + 68087 = 68130
59 + 68071 = 68130
71 + 68059 = 68130
89 + 68041 = 68130
107 + 68023 = 68130

Showing the first eight; more decompositions exist.
