Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669380, here are decompositions:

29 + 8669351 = 8669380
47 + 8669333 = 8669380
101 + 8669279 = 8669380
131 + 8669249 = 8669380
173 + 8669207 = 8669380
191 + 8669189 = 8669380
257 + 8669123 = 8669380
263 + 8669117 = 8669380

Showing the first eight; more decompositions exist.
