Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681472, here are decompositions:

5 + 8681467 = 8681472
43 + 8681429 = 8681472
71 + 8681401 = 8681472
103 + 8681369 = 8681472
109 + 8681363 = 8681472
113 + 8681359 = 8681472
131 + 8681341 = 8681472
181 + 8681291 = 8681472

Showing the first eight; more decompositions exist.
