Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617258, here are decompositions:

5 + 8617253 = 8617258
47 + 8617211 = 8617258
71 + 8617187 = 8617258
149 + 8617109 = 8617258
257 + 8617001 = 8617258
269 + 8616989 = 8617258
311 + 8616947 = 8617258
347 + 8616911 = 8617258

Showing the first eight; more decompositions exist.
