Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654678, here are decompositions:

37 + 8654641 = 8654678
61 + 8654617 = 8654678
157 + 8654521 = 8654678
211 + 8654467 = 8654678
379 + 8654299 = 8654678
397 + 8654281 = 8654678
421 + 8654257 = 8654678
457 + 8654221 = 8654678

Showing the first eight; more decompositions exist.
