Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511550, here are decompositions:

31 + 511519 = 511550
43 + 511507 = 511550
73 + 511477 = 511550
97 + 511453 = 511550
103 + 511447 = 511550
163 + 511387 = 511550
199 + 511351 = 511550
223 + 511327 = 511550

Showing the first eight; more decompositions exist.
