Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743748, here are decompositions:

31 + 8743717 = 8743748
37 + 8743711 = 8743748
67 + 8743681 = 8743748
109 + 8743639 = 8743748
127 + 8743621 = 8743748
151 + 8743597 = 8743748
199 + 8743549 = 8743748
331 + 8743417 = 8743748

Showing the first eight; more decompositions exist.
