Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699378, here are decompositions:

67 + 8699311 = 8699378
109 + 8699269 = 8699378
139 + 8699239 = 8699378
151 + 8699227 = 8699378
199 + 8699179 = 8699378
211 + 8699167 = 8699378
409 + 8698969 = 8699378
439 + 8698939 = 8699378

Showing the first eight; more decompositions exist.
