Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743628, here are decompositions:

7 + 8743621 = 8743628
31 + 8743597 = 8743628
67 + 8743561 = 8743628
79 + 8743549 = 8743628
97 + 8743531 = 8743628
139 + 8743489 = 8743628
181 + 8743447 = 8743628
211 + 8743417 = 8743628

Showing the first eight; more decompositions exist.
