Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655164, here are decompositions:

61 + 8655103 = 8655164
127 + 8655037 = 8655164
157 + 8655007 = 8655164
223 + 8654941 = 8655164
523 + 8654641 = 8655164
547 + 8654617 = 8655164
601 + 8654563 = 8655164
643 + 8654521 = 8655164

Showing the first eight; more decompositions exist.
