Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513180, here are decompositions:

7 + 513173 = 513180
11 + 513169 = 513180
13 + 513167 = 513180
23 + 513157 = 513180
43 + 513137 = 513180
71 + 513109 = 513180
79 + 513101 = 513180
97 + 513083 = 513180

Showing the first eight; more decompositions exist.
