Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699090, here are decompositions:

13 + 8699077 = 8699090
151 + 8698939 = 8699090
157 + 8698933 = 8699090
229 + 8698861 = 8699090
271 + 8698819 = 8699090
277 + 8698813 = 8699090
313 + 8698777 = 8699090
409 + 8698681 = 8699090

Showing the first eight; more decompositions exist.
