Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697872, here are decompositions:

3 + 8697869 = 8697872
13 + 8697859 = 8697872
61 + 8697811 = 8697872
103 + 8697769 = 8697872
181 + 8697691 = 8697872
373 + 8697499 = 8697872
439 + 8697433 = 8697872
571 + 8697301 = 8697872

Showing the first eight; more decompositions exist.
