Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634972, here are decompositions:

11 + 8634961 = 8634972
83 + 8634889 = 8634972
89 + 8634883 = 8634972
109 + 8634863 = 8634972
113 + 8634859 = 8634972
131 + 8634841 = 8634972
149 + 8634823 = 8634972
211 + 8634761 = 8634972

Showing the first eight; more decompositions exist.
