Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628580, here are decompositions:

29 + 8628551 = 8628580
101 + 8628479 = 8628580
131 + 8628449 = 8628580
137 + 8628443 = 8628580
173 + 8628407 = 8628580
197 + 8628383 = 8628580
227 + 8628353 = 8628580
347 + 8628233 = 8628580

Showing the first eight; more decompositions exist.
