Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654890, here are decompositions:

17 + 8654873 = 8654890
53 + 8654837 = 8654890
131 + 8654759 = 8654890
137 + 8654753 = 8654890
227 + 8654663 = 8654890
269 + 8654621 = 8654890
281 + 8654609 = 8654890
311 + 8654579 = 8654890

Showing the first eight; more decompositions exist.
