Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678904, here are decompositions:

5 + 8678899 = 8678904
11 + 8678893 = 8678904
41 + 8678863 = 8678904
53 + 8678851 = 8678904
71 + 8678833 = 8678904
83 + 8678821 = 8678904
127 + 8678777 = 8678904
131 + 8678773 = 8678904

Showing the first eight; more decompositions exist.
