Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137172, here are decompositions:

19 + 137153 = 137172
29 + 137143 = 137172
41 + 137131 = 137172
53 + 137119 = 137172
83 + 137089 = 137172
173 + 136999 = 137172
179 + 136993 = 137172
181 + 136991 = 137172

Showing the first eight; more decompositions exist.
