Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748724, here are decompositions:

11 + 8748713 = 8748724
71 + 8748653 = 8748724
137 + 8748587 = 8748724
251 + 8748473 = 8748724
293 + 8748431 = 8748724
311 + 8748413 = 8748724
401 + 8748323 = 8748724
443 + 8748281 = 8748724

Showing the first eight; more decompositions exist.
