Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706820, here are decompositions:

29 + 8706791 = 8706820
113 + 8706707 = 8706820
149 + 8706671 = 8706820
173 + 8706647 = 8706820
233 + 8706587 = 8706820
251 + 8706569 = 8706820
263 + 8706557 = 8706820
293 + 8706527 = 8706820

Showing the first eight; more decompositions exist.
