Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654390, here are decompositions:

103 + 8654287 = 8654390
109 + 8654281 = 8654390
373 + 8654017 = 8654390
379 + 8654011 = 8654390
487 + 8653903 = 8654390
499 + 8653891 = 8654390
601 + 8653789 = 8654390
673 + 8653717 = 8654390

Showing the first eight; more decompositions exist.
