Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578526, here are decompositions:

17 + 578509 = 578526
23 + 578503 = 578526
29 + 578497 = 578526
37 + 578489 = 578526
43 + 578483 = 578526
59 + 578467 = 578526
73 + 578453 = 578526
107 + 578419 = 578526

Showing the first eight; more decompositions exist.
