Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671100, here are decompositions:

3 + 8671097 = 8671100
37 + 8671063 = 8671100
43 + 8671057 = 8671100
103 + 8670997 = 8671100
157 + 8670943 = 8671100
181 + 8670919 = 8671100
349 + 8670751 = 8671100
397 + 8670703 = 8671100

Showing the first eight; more decompositions exist.
