Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520390, here are decompositions:

11 + 520379 = 520390
29 + 520361 = 520390
41 + 520349 = 520390
83 + 520307 = 520390
149 + 520241 = 520390
197 + 520193 = 520390
239 + 520151 = 520390
317 + 520073 = 520390

Showing the first eight; more decompositions exist.
