Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747228, here are decompositions:

37 + 8747191 = 8747228
109 + 8747119 = 8747228
157 + 8747071 = 8747228
229 + 8746999 = 8747228
271 + 8746957 = 8747228
307 + 8746921 = 8747228
349 + 8746879 = 8747228
367 + 8746861 = 8747228

Showing the first eight; more decompositions exist.
