Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678580, here are decompositions:

23 + 8678557 = 8678580
61 + 8678519 = 8678580
73 + 8678507 = 8678580
107 + 8678473 = 8678580
181 + 8678399 = 8678580
227 + 8678353 = 8678580
241 + 8678339 = 8678580
257 + 8678323 = 8678580

Showing the first eight; more decompositions exist.
