Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724510, here are decompositions:

13 + 8724497 = 8724510
17 + 8724493 = 8724510
23 + 8724487 = 8724510
31 + 8724479 = 8724510
43 + 8724467 = 8724510
73 + 8724437 = 8724510
89 + 8724421 = 8724510
139 + 8724371 = 8724510

Showing the first eight; more decompositions exist.
