Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634580, here are decompositions:

23 + 8634557 = 8634580
29 + 8634551 = 8634580
41 + 8634539 = 8634580
83 + 8634497 = 8634580
113 + 8634467 = 8634580
131 + 8634449 = 8634580
167 + 8634413 = 8634580
197 + 8634383 = 8634580

Showing the first eight; more decompositions exist.
