Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743186, here are decompositions:

17 + 8743169 = 8743186
47 + 8743139 = 8743186
83 + 8743103 = 8743186
107 + 8743079 = 8743186
149 + 8743037 = 8743186
167 + 8743019 = 8743186
269 + 8742917 = 8743186
509 + 8742677 = 8743186

Showing the first eight; more decompositions exist.
