Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671618, here are decompositions:

29 + 8671589 = 8671618
101 + 8671517 = 8671618
107 + 8671511 = 8671618
149 + 8671469 = 8671618
191 + 8671427 = 8671618
251 + 8671367 = 8671618
257 + 8671361 = 8671618
311 + 8671307 = 8671618

Showing the first eight; more decompositions exist.
