Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662378, here are decompositions:

29 + 8662349 = 8662378
41 + 8662337 = 8662378
59 + 8662319 = 8662378
191 + 8662187 = 8662378
227 + 8662151 = 8662378
251 + 8662127 = 8662378
269 + 8662109 = 8662378
359 + 8662019 = 8662378

Showing the first eight; more decompositions exist.
