Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671658, here are decompositions:

19 + 8671639 = 8671658
109 + 8671549 = 8671658
139 + 8671519 = 8671658
157 + 8671501 = 8671658
211 + 8671447 = 8671658
277 + 8671381 = 8671658
337 + 8671321 = 8671658
367 + 8671291 = 8671658

Showing the first eight; more decompositions exist.
