Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697428, here are decompositions:

127 + 8697301 = 8697428
151 + 8697277 = 8697428
331 + 8697097 = 8697428
367 + 8697061 = 8697428
379 + 8697049 = 8697428
661 + 8696767 = 8697428
739 + 8696689 = 8697428
757 + 8696671 = 8697428

Showing the first eight; more decompositions exist.
