Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578980, here are decompositions:

23 + 578957 = 578980
137 + 578843 = 578980
191 + 578789 = 578980
239 + 578741 = 578980
251 + 578729 = 578980
293 + 578687 = 578980
359 + 578621 = 578980
383 + 578597 = 578980

Showing the first eight; more decompositions exist.
