Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605506, here are decompositions:

5 + 8605501 = 8605506
37 + 8605469 = 8605506
43 + 8605463 = 8605506
59 + 8605447 = 8605506
73 + 8605433 = 8605506
103 + 8605403 = 8605506
127 + 8605379 = 8605506
137 + 8605369 = 8605506

Showing the first eight; more decompositions exist.
