Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641212, here are decompositions:

79 + 8641133 = 8641212
149 + 8641063 = 8641212
263 + 8640949 = 8641212
353 + 8640859 = 8641212
389 + 8640823 = 8641212
431 + 8640781 = 8641212
479 + 8640733 = 8641212
499 + 8640713 = 8641212

Showing the first eight; more decompositions exist.
