Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478530, here are decompositions:

7 + 478523 = 478530
37 + 478493 = 478530
47 + 478483 = 478530
71 + 478459 = 478530
79 + 478451 = 478530
89 + 478441 = 478530
97 + 478433 = 478530
103 + 478427 = 478530

Showing the first eight; more decompositions exist.
