Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698820, here are decompositions:

7 + 8698813 = 8698820
19 + 8698801 = 8698820
43 + 8698777 = 8698820
139 + 8698681 = 8698820
181 + 8698639 = 8698820
199 + 8698621 = 8698820
223 + 8698597 = 8698820
271 + 8698549 = 8698820

Showing the first eight; more decompositions exist.
