Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698778, here are decompositions:

79 + 8698699 = 8698778
97 + 8698681 = 8698778
139 + 8698639 = 8698778
157 + 8698621 = 8698778
181 + 8698597 = 8698778
229 + 8698549 = 8698778
379 + 8698399 = 8698778
409 + 8698369 = 8698778

Showing the first eight; more decompositions exist.
