Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68172, here are decompositions:

11 + 68161 = 68172
31 + 68141 = 68172
59 + 68113 = 68172
61 + 68111 = 68172
73 + 68099 = 68172
101 + 68071 = 68172
113 + 68059 = 68172
131 + 68041 = 68172

Showing the first eight; more decompositions exist.
