Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78580, here are decompositions:

3 + 78577 = 78580
11 + 78569 = 78580
41 + 78539 = 78580
71 + 78509 = 78580
83 + 78497 = 78580
101 + 78479 = 78580
113 + 78467 = 78580
179 + 78401 = 78580

Showing the first eight; more decompositions exist.
