Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743660, here are decompositions:

71 + 8743589 = 8743660
89 + 8743571 = 8743660
113 + 8743547 = 8743660
239 + 8743421 = 8743660
251 + 8743409 = 8743660
281 + 8743379 = 8743660
293 + 8743367 = 8743660
311 + 8743349 = 8743660

Showing the first eight; more decompositions exist.
