Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743200, here are decompositions:

31 + 8743169 = 8743200
61 + 8743139 = 8743200
79 + 8743121 = 8743200
97 + 8743103 = 8743200
101 + 8743099 = 8743200
113 + 8743087 = 8743200
157 + 8743043 = 8743200
163 + 8743037 = 8743200

Showing the first eight; more decompositions exist.
