Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747418, here are decompositions:

11 + 8747407 = 8747418
37 + 8747381 = 8747418
89 + 8747329 = 8747418
157 + 8747261 = 8747418
167 + 8747251 = 8747418
227 + 8747191 = 8747418
307 + 8747111 = 8747418
347 + 8747071 = 8747418

Showing the first eight; more decompositions exist.
