Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632978, here are decompositions:

41 + 8632937 = 8632978
47 + 8632931 = 8632978
149 + 8632829 = 8632978
251 + 8632727 = 8632978
311 + 8632667 = 8632978
317 + 8632661 = 8632978
449 + 8632529 = 8632978
491 + 8632487 = 8632978

Showing the first eight; more decompositions exist.
