Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578542, here are decompositions:

5 + 578537 = 578542
53 + 578489 = 578542
59 + 578483 = 578542
89 + 578453 = 578542
101 + 578441 = 578542
179 + 578363 = 578542
233 + 578309 = 578542
359 + 578183 = 578542

Showing the first eight; more decompositions exist.
