Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671730, here are decompositions:

19 + 8671711 = 8671730
61 + 8671669 = 8671730
97 + 8671633 = 8671730
157 + 8671573 = 8671730
181 + 8671549 = 8671730
211 + 8671519 = 8671730
229 + 8671501 = 8671730
283 + 8671447 = 8671730

Showing the first eight; more decompositions exist.
