Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712618, here are decompositions:

7 + 8712611 = 8712618
17 + 8712601 = 8712618
41 + 8712577 = 8712618
71 + 8712547 = 8712618
127 + 8712491 = 8712618
197 + 8712421 = 8712618
251 + 8712367 = 8712618
269 + 8712349 = 8712618

Showing the first eight; more decompositions exist.
