Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745440, here are decompositions:

3 + 8745437 = 8745440
73 + 8745367 = 8745440
97 + 8745343 = 8745440
199 + 8745241 = 8745440
241 + 8745199 = 8745440
271 + 8745169 = 8745440
307 + 8745133 = 8745440
373 + 8745067 = 8745440

Showing the first eight; more decompositions exist.
