Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687394, here are decompositions:

7 + 8687387 = 8687394
11 + 8687383 = 8687394
13 + 8687381 = 8687394
31 + 8687363 = 8687394
73 + 8687321 = 8687394
103 + 8687291 = 8687394
167 + 8687227 = 8687394
181 + 8687213 = 8687394

Showing the first eight; more decompositions exist.
