Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722678, here are decompositions:

5 + 8722673 = 8722678
17 + 8722661 = 8722678
47 + 8722631 = 8722678
71 + 8722607 = 8722678
137 + 8722541 = 8722678
179 + 8722499 = 8722678
269 + 8722409 = 8722678
311 + 8722367 = 8722678

Showing the first eight; more decompositions exist.
