Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8695820, here are decompositions:

13 + 8695807 = 8695820
73 + 8695747 = 8695820
97 + 8695723 = 8695820
139 + 8695681 = 8695820
157 + 8695663 = 8695820
181 + 8695639 = 8695820
229 + 8695591 = 8695820
271 + 8695549 = 8695820

Showing the first eight; more decompositions exist.
