Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652580, here are decompositions:

17 + 8652563 = 8652580
29 + 8652551 = 8652580
149 + 8652431 = 8652580
173 + 8652407 = 8652580
179 + 8652401 = 8652580
191 + 8652389 = 8652580
281 + 8652299 = 8652580
317 + 8652263 = 8652580

Showing the first eight; more decompositions exist.
