Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637212, here are decompositions:

61 + 8637151 = 8637212
79 + 8637133 = 8637212
109 + 8637103 = 8637212
151 + 8637061 = 8637212
223 + 8636989 = 8637212
313 + 8636899 = 8637212
373 + 8636839 = 8637212
421 + 8636791 = 8637212

Showing the first eight; more decompositions exist.
