Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654978, here are decompositions:

19 + 8654959 = 8654978
37 + 8654941 = 8654978
61 + 8654917 = 8654978
139 + 8654839 = 8654978
229 + 8654749 = 8654978
337 + 8654641 = 8654978
457 + 8654521 = 8654978
547 + 8654431 = 8654978

Showing the first eight; more decompositions exist.
