Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667582, here are decompositions:

19 + 8667563 = 8667582
23 + 8667559 = 8667582
43 + 8667539 = 8667582
61 + 8667521 = 8667582
71 + 8667511 = 8667582
151 + 8667431 = 8667582
163 + 8667419 = 8667582
179 + 8667403 = 8667582

Showing the first eight; more decompositions exist.
