Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667686, here are decompositions:

73 + 8667613 = 8667686
127 + 8667559 = 8667686
229 + 8667457 = 8667686
283 + 8667403 = 8667686
337 + 8667349 = 8667686
367 + 8667319 = 8667686
373 + 8667313 = 8667686
397 + 8667289 = 8667686

Showing the first eight; more decompositions exist.
