Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578080, here are decompositions:

3 + 578077 = 578080
17 + 578063 = 578080
59 + 578021 = 578080
101 + 577979 = 578080
149 + 577931 = 578080
179 + 577901 = 578080
263 + 577817 = 578080
281 + 577799 = 578080

Showing the first eight; more decompositions exist.
