Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651580, here are decompositions:

31 + 8651549 = 8651580
37 + 8651543 = 8651580
43 + 8651537 = 8651580
73 + 8651507 = 8651580
79 + 8651501 = 8651580
137 + 8651443 = 8651580
151 + 8651429 = 8651580
181 + 8651399 = 8651580

Showing the first eight; more decompositions exist.
