Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653378, here are decompositions:

5 + 8653373 = 8653378
17 + 8653361 = 8653378
59 + 8653319 = 8653378
137 + 8653241 = 8653378
179 + 8653199 = 8653378
257 + 8653121 = 8653378
347 + 8653031 = 8653378
431 + 8652947 = 8653378

Showing the first eight; more decompositions exist.
