Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605994, here are decompositions:

31 + 8605963 = 8605994
151 + 8605843 = 8605994
181 + 8605813 = 8605994
193 + 8605801 = 8605994
433 + 8605561 = 8605994
547 + 8605447 = 8605994
757 + 8605237 = 8605994
823 + 8605171 = 8605994

Showing the first eight; more decompositions exist.
