Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747144, here are decompositions:

61 + 8747083 = 8747144
73 + 8747071 = 8747144
103 + 8747041 = 8747144
181 + 8746963 = 8747144
223 + 8746921 = 8747144
271 + 8746873 = 8747144
283 + 8746861 = 8747144
331 + 8746813 = 8747144

Showing the first eight; more decompositions exist.
