Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578120, here are decompositions:

3 + 578117 = 578120
43 + 578077 = 578120
73 + 578047 = 578120
79 + 578041 = 578120
139 + 577981 = 578120
163 + 577957 = 578120
181 + 577939 = 578120
211 + 577909 = 578120

Showing the first eight; more decompositions exist.
