Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675720, here are decompositions:

43 + 8675677 = 8675720
199 + 8675521 = 8675720
211 + 8675509 = 8675720
271 + 8675449 = 8675720
307 + 8675413 = 8675720
337 + 8675383 = 8675720
349 + 8675371 = 8675720
379 + 8675341 = 8675720

Showing the first eight; more decompositions exist.
