Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671830, here are decompositions:

19 + 8671811 = 8671830
61 + 8671769 = 8671830
109 + 8671721 = 8671830
191 + 8671639 = 8671830
197 + 8671633 = 8671830
199 + 8671631 = 8671830
241 + 8671589 = 8671830
257 + 8671573 = 8671830

Showing the first eight; more decompositions exist.
