Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636980, here are decompositions:

59 + 8636921 = 8636980
71 + 8636909 = 8636980
179 + 8636801 = 8636980
239 + 8636741 = 8636980
347 + 8636633 = 8636980
353 + 8636627 = 8636980
389 + 8636591 = 8636980
431 + 8636549 = 8636980

Showing the first eight; more decompositions exist.
