Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170140, here are decompositions:

17 + 170123 = 170140
29 + 170111 = 170140
41 + 170099 = 170140
59 + 170081 = 170140
83 + 170057 = 170140
137 + 170003 = 170140
149 + 169991 = 170140
197 + 169943 = 170140

Showing the first eight; more decompositions exist.
