Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671316, here are decompositions:

67 + 8671249 = 8671316
97 + 8671219 = 8671316
139 + 8671177 = 8671316
307 + 8671009 = 8671316
373 + 8670943 = 8671316
397 + 8670919 = 8671316
607 + 8670709 = 8671316
613 + 8670703 = 8671316

Showing the first eight; more decompositions exist.
