Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170112, here are decompositions:

11 + 170101 = 170112
13 + 170099 = 170112
31 + 170081 = 170112
83 + 170029 = 170112
109 + 170003 = 170112
179 + 169933 = 170112
193 + 169919 = 170112
199 + 169913 = 170112

Showing the first eight; more decompositions exist.
