Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578180, here are decompositions:

13 + 578167 = 578180
103 + 578077 = 578180
139 + 578041 = 578180
151 + 578029 = 578180
199 + 577981 = 578180
223 + 577957 = 578180
241 + 577939 = 578180
271 + 577909 = 578180

Showing the first eight; more decompositions exist.
