Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747556, here are decompositions:

17 + 8747539 = 8747556
29 + 8747527 = 8747556
43 + 8747513 = 8747556
67 + 8747489 = 8747556
73 + 8747483 = 8747556
137 + 8747419 = 8747556
149 + 8747407 = 8747556
227 + 8747329 = 8747556

Showing the first eight; more decompositions exist.
