Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724560, here are decompositions:

67 + 8724493 = 8724560
73 + 8724487 = 8724560
139 + 8724421 = 8724560
241 + 8724319 = 8724560
277 + 8724283 = 8724560
307 + 8724253 = 8724560
337 + 8724223 = 8724560
379 + 8724181 = 8724560

Showing the first eight; more decompositions exist.
