Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171190, here are decompositions:

11 + 171179 = 171190
23 + 171167 = 171190
29 + 171161 = 171190
59 + 171131 = 171190
113 + 171077 = 171190
137 + 171053 = 171190
167 + 171023 = 171190
233 + 170957 = 171190

Showing the first eight; more decompositions exist.
