Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667788, here are decompositions:

61 + 8667727 = 8667788
67 + 8667721 = 8667788
127 + 8667661 = 8667788
229 + 8667559 = 8667788
277 + 8667511 = 8667788
331 + 8667457 = 8667788
439 + 8667349 = 8667788
487 + 8667301 = 8667788

Showing the first eight; more decompositions exist.
