Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620128, here are decompositions:

7 + 8620121 = 8620128
17 + 8620111 = 8620128
19 + 8620109 = 8620128
59 + 8620069 = 8620128
79 + 8620049 = 8620128
131 + 8619997 = 8620128
191 + 8619937 = 8620128
269 + 8619859 = 8620128

Showing the first eight; more decompositions exist.
