Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578628, here are decompositions:

7 + 578621 = 578628
19 + 578609 = 578628
31 + 578597 = 578628
41 + 578587 = 578628
47 + 578581 = 578628
131 + 578497 = 578628
139 + 578489 = 578628
151 + 578477 = 578628

Showing the first eight; more decompositions exist.
