Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743138, here are decompositions:

17 + 8743121 = 8743138
59 + 8743079 = 8743138
71 + 8743067 = 8743138
101 + 8743037 = 8743138
137 + 8743001 = 8743138
197 + 8742941 = 8743138
251 + 8742887 = 8743138
281 + 8742857 = 8743138

Showing the first eight; more decompositions exist.
