Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637040, here are decompositions:

23 + 8637017 = 8637040
53 + 8636987 = 8637040
131 + 8636909 = 8637040
239 + 8636801 = 8637040
281 + 8636759 = 8637040
449 + 8636591 = 8637040
491 + 8636549 = 8637040
617 + 8636423 = 8637040

Showing the first eight; more decompositions exist.
