Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747628, here are decompositions:

5 + 8747623 = 8747628
11 + 8747617 = 8747628
67 + 8747561 = 8747628
89 + 8747539 = 8747628
101 + 8747527 = 8747628
139 + 8747489 = 8747628
157 + 8747471 = 8747628
367 + 8747261 = 8747628

Showing the first eight; more decompositions exist.
