Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637100, here are decompositions:

41 + 8637059 = 8637100
47 + 8637053 = 8637100
83 + 8637017 = 8637100
113 + 8636987 = 8637100
179 + 8636921 = 8637100
191 + 8636909 = 8637100
281 + 8636819 = 8637100
359 + 8636741 = 8637100

Showing the first eight; more decompositions exist.
