Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671712, here are decompositions:

3 + 8671709 = 8671712
43 + 8671669 = 8671712
73 + 8671639 = 8671712
79 + 8671633 = 8671712
139 + 8671573 = 8671712
163 + 8671549 = 8671712
193 + 8671519 = 8671712
211 + 8671501 = 8671712

Showing the first eight; more decompositions exist.
