Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747646, here are decompositions:

23 + 8747623 = 8747646
29 + 8747617 = 8747646
43 + 8747603 = 8747646
67 + 8747579 = 8747646
73 + 8747573 = 8747646
107 + 8747539 = 8747646
157 + 8747489 = 8747646
163 + 8747483 = 8747646

Showing the first eight; more decompositions exist.
