Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667782, here are decompositions:

61 + 8667721 = 8667782
181 + 8667601 = 8667782
223 + 8667559 = 8667782
271 + 8667511 = 8667782
379 + 8667403 = 8667782
433 + 8667349 = 8667782
463 + 8667319 = 8667782
631 + 8667151 = 8667782

Showing the first eight; more decompositions exist.
