Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171130, here are decompositions:

53 + 171077 = 171130
83 + 171047 = 171130
101 + 171029 = 171130
107 + 171023 = 171130
173 + 170957 = 171130
257 + 170873 = 171130
293 + 170837 = 171130
317 + 170813 = 171130

Showing the first eight; more decompositions exist.
