Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672986, here are decompositions:

17 + 8672969 = 8672986
53 + 8672933 = 8672986
59 + 8672927 = 8672986
89 + 8672897 = 8672986
167 + 8672819 = 8672986
197 + 8672789 = 8672986
263 + 8672723 = 8672986
347 + 8672639 = 8672986

Showing the first eight; more decompositions exist.
