Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697668, here are decompositions:

61 + 8697607 = 8697668
157 + 8697511 = 8697668
367 + 8697301 = 8697668
541 + 8697127 = 8697668
571 + 8697097 = 8697668
607 + 8697061 = 8697668
619 + 8697049 = 8697668
631 + 8697037 = 8697668

Showing the first eight; more decompositions exist.
