Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171292, here are decompositions:

29 + 171263 = 171292
41 + 171251 = 171292
59 + 171233 = 171292
89 + 171203 = 171292
113 + 171179 = 171292
131 + 171161 = 171292
239 + 171053 = 171292
263 + 171029 = 171292

Showing the first eight; more decompositions exist.
