Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673556, here are decompositions:

137 + 8673419 = 8673556
167 + 8673389 = 8673556
179 + 8673377 = 8673556
197 + 8673359 = 8673556
263 + 8673293 = 8673556
347 + 8673209 = 8673556
389 + 8673167 = 8673556
443 + 8673113 = 8673556

Showing the first eight; more decompositions exist.
