Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657394, here are decompositions:

7 + 8657387 = 8657394
13 + 8657381 = 8657394
17 + 8657377 = 8657394
37 + 8657357 = 8657394
61 + 8657333 = 8657394
71 + 8657323 = 8657394
103 + 8657291 = 8657394
157 + 8657237 = 8657394

Showing the first eight; more decompositions exist.
