Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640134, here are decompositions:

157 + 8639977 = 8640134
211 + 8639923 = 8640134
271 + 8639863 = 8640134
331 + 8639803 = 8640134
337 + 8639797 = 8640134
421 + 8639713 = 8640134
487 + 8639647 = 8640134
571 + 8639563 = 8640134

Showing the first eight; more decompositions exist.
