Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667642, here are decompositions:

29 + 8667613 = 8667642
31 + 8667611 = 8667642
41 + 8667601 = 8667642
79 + 8667563 = 8667642
83 + 8667559 = 8667642
103 + 8667539 = 8667642
131 + 8667511 = 8667642
211 + 8667431 = 8667642

Showing the first eight; more decompositions exist.
