Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636944, here are decompositions:

23 + 8636921 = 8636944
311 + 8636633 = 8636944
317 + 8636627 = 8636944
353 + 8636591 = 8636944
401 + 8636543 = 8636944
431 + 8636513 = 8636944
521 + 8636423 = 8636944
557 + 8636387 = 8636944

Showing the first eight; more decompositions exist.
