Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743328, here are decompositions:

19 + 8743309 = 8743328
67 + 8743261 = 8743328
229 + 8743099 = 8743328
241 + 8743087 = 8743328
331 + 8742997 = 8743328
397 + 8742931 = 8743328
409 + 8742919 = 8743328
541 + 8742787 = 8743328

Showing the first eight; more decompositions exist.
