Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739040, here are decompositions:

17 + 8739023 = 8739040
83 + 8738957 = 8739040
197 + 8738843 = 8739040
227 + 8738813 = 8739040
239 + 8738801 = 8739040
257 + 8738783 = 8739040
281 + 8738759 = 8739040
311 + 8738729 = 8739040

Showing the first eight; more decompositions exist.
