Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678972, here are decompositions:

31 + 8678941 = 8678972
73 + 8678899 = 8678972
79 + 8678893 = 8678972
109 + 8678863 = 8678972
139 + 8678833 = 8678972
151 + 8678821 = 8678972
193 + 8678779 = 8678972
199 + 8678773 = 8678972

Showing the first eight; more decompositions exist.
