Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740284, here are decompositions:

11 + 8740273 = 8740284
97 + 8740187 = 8740284
101 + 8740183 = 8740284
127 + 8740157 = 8740284
167 + 8740117 = 8740284
173 + 8740111 = 8740284
197 + 8740087 = 8740284
281 + 8740003 = 8740284

Showing the first eight; more decompositions exist.
