Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511574, here are decompositions:

67 + 511507 = 511574
97 + 511477 = 511574
127 + 511447 = 511574
157 + 511417 = 511574
223 + 511351 = 511574
241 + 511333 = 511574
277 + 511297 = 511574
313 + 511261 = 511574

Showing the first eight; more decompositions exist.
