Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612678, here are decompositions:

7 + 8612671 = 8612678
37 + 8612641 = 8612678
97 + 8612581 = 8612678
181 + 8612497 = 8612678
199 + 8612479 = 8612678
241 + 8612437 = 8612678
331 + 8612347 = 8612678
367 + 8612311 = 8612678

Showing the first eight; more decompositions exist.
