Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724522, here are decompositions:

11 + 8724511 = 8724522
29 + 8724493 = 8724522
43 + 8724479 = 8724522
61 + 8724461 = 8724522
101 + 8724421 = 8724522
151 + 8724371 = 8724522
193 + 8724329 = 8724522
199 + 8724323 = 8724522

Showing the first eight; more decompositions exist.
