Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613478, here are decompositions:

17 + 8613461 = 8613478
131 + 8613347 = 8613478
149 + 8613329 = 8613478
179 + 8613299 = 8613478
197 + 8613281 = 8613478
257 + 8613221 = 8613478
317 + 8613161 = 8613478
389 + 8613089 = 8613478

Showing the first eight; more decompositions exist.
