Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747724, here are decompositions:

23 + 8747701 = 8747724
47 + 8747677 = 8747724
71 + 8747653 = 8747724
101 + 8747623 = 8747724
107 + 8747617 = 8747724
151 + 8747573 = 8747724
163 + 8747561 = 8747724
197 + 8747527 = 8747724

Showing the first eight; more decompositions exist.
