Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618004, here are decompositions:

11 + 8617993 = 8618004
13 + 8617991 = 8618004
61 + 8617943 = 8618004
71 + 8617933 = 8618004
127 + 8617877 = 8618004
167 + 8617837 = 8618004
181 + 8617823 = 8618004
251 + 8617753 = 8618004

Showing the first eight; more decompositions exist.
