Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78578, here are decompositions:

7 + 78571 = 78578
37 + 78541 = 78578
61 + 78517 = 78578
67 + 78511 = 78578
139 + 78439 = 78578
151 + 78427 = 78578
211 + 78367 = 78578
271 + 78307 = 78578

Showing the first eight; more decompositions exist.
