Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671504, here are decompositions:

3 + 8671501 = 8671504
5 + 8671499 = 8671504
41 + 8671463 = 8671504
47 + 8671457 = 8671504
137 + 8671367 = 8671504
173 + 8671331 = 8671504
197 + 8671307 = 8671504
311 + 8671193 = 8671504

Showing the first eight; more decompositions exist.
