Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667446, here are decompositions:

19 + 8667427 = 8667446
43 + 8667403 = 8667446
97 + 8667349 = 8667446
127 + 8667319 = 8667446
157 + 8667289 = 8667446
367 + 8667079 = 8667446
457 + 8666989 = 8667446
607 + 8666839 = 8667446

Showing the first eight; more decompositions exist.
