Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699428, here are decompositions:

5 + 8699423 = 8699428
41 + 8699387 = 8699428
47 + 8699381 = 8699428
131 + 8699297 = 8699428
149 + 8699279 = 8699428
191 + 8699237 = 8699428
359 + 8699069 = 8699428
389 + 8699039 = 8699428

Showing the first eight; more decompositions exist.
