Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635020, here are decompositions:

59 + 8634961 = 8635020
73 + 8634947 = 8635020
103 + 8634917 = 8635020
113 + 8634907 = 8635020
131 + 8634889 = 8635020
137 + 8634883 = 8635020
139 + 8634881 = 8635020
157 + 8634863 = 8635020

Showing the first eight; more decompositions exist.
