Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749284, here are decompositions:

41 + 8749243 = 8749284
151 + 8749133 = 8749284
157 + 8749127 = 8749284
163 + 8749121 = 8749284
197 + 8749087 = 8749284
277 + 8749007 = 8749284
283 + 8749001 = 8749284
293 + 8748991 = 8749284

Showing the first eight; more decompositions exist.
