Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102358, here are decompositions:

29 + 102329 = 102358
41 + 102317 = 102358
59 + 102299 = 102358
107 + 102251 = 102358
167 + 102191 = 102358
197 + 102161 = 102358
251 + 102107 = 102358
257 + 102101 = 102358

Showing the first eight; more decompositions exist.
