Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634512, here are decompositions:

31 + 8634481 = 8634512
43 + 8634469 = 8634512
349 + 8634163 = 8634512
373 + 8634139 = 8634512
379 + 8634133 = 8634512
463 + 8634049 = 8634512
541 + 8633971 = 8634512
571 + 8633941 = 8634512

Showing the first eight; more decompositions exist.
