Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511542, here are decompositions:

19 + 511523 = 511542
23 + 511519 = 511542
79 + 511463 = 511542
89 + 511453 = 511542
103 + 511439 = 511542
151 + 511391 = 511542
181 + 511361 = 511542
191 + 511351 = 511542

Showing the first eight; more decompositions exist.
