Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478542, here are decompositions:

11 + 478531 = 478542
19 + 478523 = 478542
59 + 478483 = 478542
61 + 478481 = 478542
83 + 478459 = 478542
89 + 478453 = 478542
101 + 478441 = 478542
109 + 478433 = 478542

Showing the first eight; more decompositions exist.
