Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671144, here are decompositions:

11 + 8671133 = 8671144
17 + 8671127 = 8671144
47 + 8671097 = 8671144
113 + 8671031 = 8671144
137 + 8671007 = 8671144
197 + 8670947 = 8671144
257 + 8670887 = 8671144
281 + 8670863 = 8671144

Showing the first eight; more decompositions exist.
