Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671764, here are decompositions:

43 + 8671721 = 8671764
53 + 8671711 = 8671764
67 + 8671697 = 8671764
131 + 8671633 = 8671764
181 + 8671583 = 8671764
191 + 8671573 = 8671764
263 + 8671501 = 8671764
293 + 8671471 = 8671764

Showing the first eight; more decompositions exist.
