Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667672, here are decompositions:

11 + 8667661 = 8667672
19 + 8667653 = 8667672
31 + 8667641 = 8667672
59 + 8667613 = 8667672
61 + 8667611 = 8667672
71 + 8667601 = 8667672
109 + 8667563 = 8667672
113 + 8667559 = 8667672

Showing the first eight; more decompositions exist.
