Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698578, here are decompositions:

19 + 8698559 = 8698578
29 + 8698549 = 8698578
61 + 8698517 = 8698578
79 + 8698499 = 8698578
127 + 8698451 = 8698578
157 + 8698421 = 8698578
179 + 8698399 = 8698578
181 + 8698397 = 8698578

Showing the first eight; more decompositions exist.
