Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513206, here are decompositions:

3 + 513203 = 513206
37 + 513169 = 513206
97 + 513109 = 513206
103 + 513103 = 513206
139 + 513067 = 513206
193 + 513013 = 513206
229 + 512977 = 513206
277 + 512929 = 513206

Showing the first eight; more decompositions exist.
