Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743218, here are decompositions:

5 + 8743213 = 8743218
79 + 8743139 = 8743218
97 + 8743121 = 8743218
131 + 8743087 = 8743218
139 + 8743079 = 8743218
151 + 8743067 = 8743218
181 + 8743037 = 8743218
191 + 8743027 = 8743218

Showing the first eight; more decompositions exist.
