Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659378, here are decompositions:

89 + 8659289 = 8659378
197 + 8659181 = 8659378
257 + 8659121 = 8659378
281 + 8659097 = 8659378
311 + 8659067 = 8659378
317 + 8659061 = 8659378
359 + 8659019 = 8659378
389 + 8658989 = 8659378

Showing the first eight; more decompositions exist.
