Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170888, here are decompositions:

7 + 170881 = 170888
31 + 170857 = 170888
37 + 170851 = 170888
61 + 170827 = 170888
79 + 170809 = 170888
127 + 170761 = 170888
139 + 170749 = 170888
181 + 170707 = 170888

Showing the first eight; more decompositions exist.
