Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743730, here are decompositions:

13 + 8743717 = 8743730
19 + 8743711 = 8743730
97 + 8743633 = 8743730
109 + 8743621 = 8743730
181 + 8743549 = 8743730
199 + 8743531 = 8743730
241 + 8743489 = 8743730
271 + 8743459 = 8743730

Showing the first eight; more decompositions exist.
