Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604990, here are decompositions:

7 + 8604983 = 8604990
13 + 8604977 = 8604990
29 + 8604961 = 8604990
47 + 8604943 = 8604990
127 + 8604863 = 8604990
167 + 8604823 = 8604990
179 + 8604811 = 8604990
181 + 8604809 = 8604990

Showing the first eight; more decompositions exist.
