Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724498, here are decompositions:

5 + 8724493 = 8724498
11 + 8724487 = 8724498
19 + 8724479 = 8724498
31 + 8724467 = 8724498
37 + 8724461 = 8724498
61 + 8724437 = 8724498
127 + 8724371 = 8724498
151 + 8724347 = 8724498

Showing the first eight; more decompositions exist.
