Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158260, here are decompositions:

17 + 158243 = 158260
29 + 158231 = 158260
59 + 158201 = 158260
71 + 158189 = 158260
131 + 158129 = 158260
251 + 158009 = 158260
257 + 158003 = 158260
269 + 157991 = 158260

Showing the first eight; more decompositions exist.
