Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613378, here are decompositions:

29 + 8613349 = 8613378
31 + 8613347 = 8613378
79 + 8613299 = 8613378
97 + 8613281 = 8613378
149 + 8613229 = 8613378
157 + 8613221 = 8613378
167 + 8613211 = 8613378
197 + 8613181 = 8613378

Showing the first eight; more decompositions exist.
