Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513308, here are decompositions:

31 + 513277 = 513308
139 + 513169 = 513308
151 + 513157 = 513308
199 + 513109 = 513308
241 + 513067 = 513308
277 + 513031 = 513308
307 + 513001 = 513308
331 + 512977 = 513308

Showing the first eight; more decompositions exist.
