Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678520, here are decompositions:

13 + 8678507 = 8678520
47 + 8678473 = 8678520
73 + 8678447 = 8678520
127 + 8678393 = 8678520
157 + 8678363 = 8678520
167 + 8678353 = 8678520
181 + 8678339 = 8678520
197 + 8678323 = 8678520

Showing the first eight; more decompositions exist.
