Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697578, here are decompositions:

67 + 8697511 = 8697578
79 + 8697499 = 8697578
199 + 8697379 = 8697578
277 + 8697301 = 8697578
541 + 8697037 = 8697578
601 + 8696977 = 8697578
661 + 8696917 = 8697578
787 + 8696791 = 8697578

Showing the first eight; more decompositions exist.
