Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743528, here are decompositions:

29 + 8743499 = 8743528
107 + 8743421 = 8743528
149 + 8743379 = 8743528
179 + 8743349 = 8743528
197 + 8743331 = 8743528
251 + 8743277 = 8743528
359 + 8743169 = 8743528
389 + 8743139 = 8743528

Showing the first eight; more decompositions exist.
