Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511390, here are decompositions:

3 + 511387 = 511390
29 + 511361 = 511390
53 + 511337 = 511390
101 + 511289 = 511390
167 + 511223 = 511390
179 + 511211 = 511390
197 + 511193 = 511390
227 + 511163 = 511390

Showing the first eight; more decompositions exist.
