Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578842, here are decompositions:

3 + 578839 = 578842
23 + 578819 = 578842
53 + 578789 = 578842
101 + 578741 = 578842
113 + 578729 = 578842
149 + 578693 = 578842
233 + 578609 = 578842
239 + 578603 = 578842

Showing the first eight; more decompositions exist.
