Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743290, here are decompositions:

11 + 8743279 = 8743290
13 + 8743277 = 8743290
29 + 8743261 = 8743290
151 + 8743139 = 8743290
191 + 8743099 = 8743290
211 + 8743079 = 8743290
223 + 8743067 = 8743290
263 + 8743027 = 8743290

Showing the first eight; more decompositions exist.
