Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608520, here are decompositions:

13 + 8608507 = 8608520
31 + 8608489 = 8608520
97 + 8608423 = 8608520
163 + 8608357 = 8608520
199 + 8608321 = 8608520
229 + 8608291 = 8608520
337 + 8608183 = 8608520
373 + 8608147 = 8608520

Showing the first eight; more decompositions exist.
