Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620122, here are decompositions:

11 + 8620111 = 8620122
13 + 8620109 = 8620122
53 + 8620069 = 8620122
59 + 8620063 = 8620122
73 + 8620049 = 8620122
79 + 8620043 = 8620122
179 + 8619943 = 8620122
229 + 8619893 = 8620122

Showing the first eight; more decompositions exist.
