Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671120, here are decompositions:

23 + 8671097 = 8671120
53 + 8671067 = 8671120
89 + 8671031 = 8671120
113 + 8671007 = 8671120
131 + 8670989 = 8671120
173 + 8670947 = 8671120
179 + 8670941 = 8671120
233 + 8670887 = 8671120

Showing the first eight; more decompositions exist.
