Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671190, here are decompositions:

13 + 8671177 = 8671190
43 + 8671147 = 8671190
127 + 8671063 = 8671190
139 + 8671051 = 8671190
181 + 8671009 = 8671190
193 + 8670997 = 8671190
271 + 8670919 = 8671190
379 + 8670811 = 8671190

Showing the first eight; more decompositions exist.
