Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739328, here are decompositions:

29 + 8739299 = 8739328
47 + 8739281 = 8739328
131 + 8739197 = 8739328
491 + 8738837 = 8739328
569 + 8738759 = 8739328
599 + 8738729 = 8739328
617 + 8738711 = 8739328
761 + 8738567 = 8739328

Showing the first eight; more decompositions exist.
