Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618394, here are decompositions:

7 + 8618387 = 8618394
17 + 8618377 = 8618394
67 + 8618327 = 8618394
97 + 8618297 = 8618394
101 + 8618293 = 8618394
107 + 8618287 = 8618394
137 + 8618257 = 8618394
151 + 8618243 = 8618394

Showing the first eight; more decompositions exist.
