Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667742, here are decompositions:

53 + 8667689 = 8667742
89 + 8667653 = 8667742
101 + 8667641 = 8667742
131 + 8667611 = 8667742
179 + 8667563 = 8667742
311 + 8667431 = 8667742
443 + 8667299 = 8667742
563 + 8667179 = 8667742

Showing the first eight; more decompositions exist.
