Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511448, here are decompositions:

31 + 511417 = 511448
61 + 511387 = 511448
97 + 511351 = 511448
151 + 511297 = 511448
211 + 511237 = 511448
271 + 511177 = 511448
277 + 511171 = 511448
337 + 511111 = 511448

Showing the first eight; more decompositions exist.
