Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478584, here are decompositions:

5 + 478579 = 478584
11 + 478573 = 478584
13 + 478571 = 478584
53 + 478531 = 478584
61 + 478523 = 478584
101 + 478483 = 478584
103 + 478481 = 478584
131 + 478453 = 478584

Showing the first eight; more decompositions exist.
