Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743188, here are decompositions:

19 + 8743169 = 8743188
67 + 8743121 = 8743188
89 + 8743099 = 8743188
101 + 8743087 = 8743188
109 + 8743079 = 8743188
151 + 8743037 = 8743188
191 + 8742997 = 8743188
211 + 8742977 = 8743188

Showing the first eight; more decompositions exist.
