Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 484640, here are decompositions:

19 + 484621 = 484640
31 + 484609 = 484640
43 + 484597 = 484640
97 + 484543 = 484640
109 + 484531 = 484640
151 + 484489 = 484640
181 + 484459 = 484640
193 + 484447 = 484640

Showing the first eight; more decompositions exist.
