Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681542, here are decompositions:

3 + 8681539 = 8681542
29 + 8681513 = 8681542
53 + 8681489 = 8681542
59 + 8681483 = 8681542
113 + 8681429 = 8681542
173 + 8681369 = 8681542
179 + 8681363 = 8681542
251 + 8681291 = 8681542

Showing the first eight; more decompositions exist.
