Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617378, here are decompositions:

5 + 8617373 = 8617378
17 + 8617361 = 8617378
59 + 8617319 = 8617378
101 + 8617277 = 8617378
167 + 8617211 = 8617378
191 + 8617187 = 8617378
269 + 8617109 = 8617378
281 + 8617097 = 8617378

Showing the first eight; more decompositions exist.
