Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578506, here are decompositions:

3 + 578503 = 578506
17 + 578489 = 578506
23 + 578483 = 578506
29 + 578477 = 578506
53 + 578453 = 578506
107 + 578399 = 578506
179 + 578327 = 578506
197 + 578309 = 578506

Showing the first eight; more decompositions exist.
