Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747736, here are decompositions:

13 + 8747723 = 8747736
47 + 8747689 = 8747736
59 + 8747677 = 8747736
83 + 8747653 = 8747736
113 + 8747623 = 8747736
157 + 8747579 = 8747736
163 + 8747573 = 8747736
197 + 8747539 = 8747736

Showing the first eight; more decompositions exist.
