Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743808, here are decompositions:

37 + 8743771 = 8743808
61 + 8743747 = 8743808
97 + 8743711 = 8743808
127 + 8743681 = 8743808
211 + 8743597 = 8743808
277 + 8743531 = 8743808
349 + 8743459 = 8743808
397 + 8743411 = 8743808

Showing the first eight; more decompositions exist.
