Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743180, here are decompositions:

11 + 8743169 = 8743180
41 + 8743139 = 8743180
59 + 8743121 = 8743180
101 + 8743079 = 8743180
113 + 8743067 = 8743180
137 + 8743043 = 8743180
179 + 8743001 = 8743180
239 + 8742941 = 8743180

Showing the first eight; more decompositions exist.
