Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724540, here are decompositions:

29 + 8724511 = 8724540
43 + 8724497 = 8724540
47 + 8724493 = 8724540
53 + 8724487 = 8724540
61 + 8724479 = 8724540
73 + 8724467 = 8724540
79 + 8724461 = 8724540
103 + 8724437 = 8724540

Showing the first eight; more decompositions exist.
