Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634980, here are decompositions:

19 + 8634961 = 8634980
73 + 8634907 = 8634980
97 + 8634883 = 8634980
139 + 8634841 = 8634980
157 + 8634823 = 8634980
229 + 8634751 = 8634980
283 + 8634697 = 8634980
313 + 8634667 = 8634980

Showing the first eight; more decompositions exist.
