Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512980, here are decompositions:

3 + 512977 = 512980
53 + 512927 = 512980
59 + 512921 = 512980
89 + 512891 = 512980
131 + 512849 = 512980
137 + 512843 = 512980
233 + 512747 = 512980
239 + 512741 = 512980

Showing the first eight; more decompositions exist.
