Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513290, here are decompositions:

7 + 513283 = 513290
13 + 513277 = 513290
181 + 513109 = 513290
223 + 513067 = 513290
277 + 513013 = 513290
313 + 512977 = 513290
331 + 512959 = 513290
373 + 512917 = 513290

Showing the first eight; more decompositions exist.
