Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743278, here are decompositions:

17 + 8743261 = 8743278
109 + 8743169 = 8743278
139 + 8743139 = 8743278
157 + 8743121 = 8743278
179 + 8743099 = 8743278
191 + 8743087 = 8743278
199 + 8743079 = 8743278
211 + 8743067 = 8743278

Showing the first eight; more decompositions exist.
