Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747184, here are decompositions:

13 + 8747171 = 8747184
73 + 8747111 = 8747184
101 + 8747083 = 8747184
113 + 8747071 = 8747184
227 + 8746957 = 8747184
263 + 8746921 = 8747184
311 + 8746873 = 8747184
337 + 8746847 = 8747184

Showing the first eight; more decompositions exist.
