Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671836, here are decompositions:

67 + 8671769 = 8671836
97 + 8671739 = 8671836
127 + 8671709 = 8671836
139 + 8671697 = 8671836
167 + 8671669 = 8671836
197 + 8671639 = 8671836
263 + 8671573 = 8671836
317 + 8671519 = 8671836

Showing the first eight; more decompositions exist.
