Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620080, here are decompositions:

11 + 8620069 = 8620080
17 + 8620063 = 8620080
31 + 8620049 = 8620080
37 + 8620043 = 8620080
83 + 8619997 = 8620080
137 + 8619943 = 8620080
197 + 8619883 = 8620080
211 + 8619869 = 8620080

Showing the first eight; more decompositions exist.
