Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671136, here are decompositions:

3 + 8671133 = 8671136
37 + 8671099 = 8671136
73 + 8671063 = 8671136
79 + 8671057 = 8671136
127 + 8671009 = 8671136
139 + 8670997 = 8671136
193 + 8670943 = 8671136
433 + 8670703 = 8671136

Showing the first eight; more decompositions exist.
