Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621174, here are decompositions:

31 + 8621143 = 8621174
73 + 8621101 = 8621174
97 + 8621077 = 8621174
127 + 8621047 = 8621174
157 + 8621017 = 8621174
181 + 8620993 = 8621174
223 + 8620951 = 8621174
277 + 8620897 = 8621174

Showing the first eight; more decompositions exist.
