Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8760820, here are decompositions:

11 + 8760809 = 8760820
41 + 8760779 = 8760820
149 + 8760671 = 8760820
179 + 8760641 = 8760820
191 + 8760629 = 8760820
197 + 8760623 = 8760820
317 + 8760503 = 8760820
353 + 8760467 = 8760820

Showing the first eight; more decompositions exist.
