Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667486, here are decompositions:

29 + 8667457 = 8667486
59 + 8667427 = 8667486
67 + 8667419 = 8667486
73 + 8667413 = 8667486
83 + 8667403 = 8667486
109 + 8667377 = 8667486
137 + 8667349 = 8667486
167 + 8667319 = 8667486

Showing the first eight; more decompositions exist.
