Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 964638, here are decompositions:

29 + 964609 = 964638
61 + 964577 = 964638
67 + 964571 = 964638
79 + 964559 = 964638
107 + 964531 = 964638
131 + 964507 = 964638
137 + 964501 = 964638
139 + 964499 = 964638

Showing the first eight; more decompositions exist.
