Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578626, here are decompositions:

5 + 578621 = 578626
17 + 578609 = 578626
23 + 578603 = 578626
29 + 578597 = 578626
53 + 578573 = 578626
89 + 578537 = 578626
137 + 578489 = 578626
149 + 578477 = 578626

Showing the first eight; more decompositions exist.
