Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743666, here are decompositions:

83 + 8743583 = 8743666
167 + 8743499 = 8743666
257 + 8743409 = 8743666
317 + 8743349 = 8743666
389 + 8743277 = 8743666
563 + 8743103 = 8743666
587 + 8743079 = 8743666
599 + 8743067 = 8743666

Showing the first eight; more decompositions exist.
