Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511992, here are decompositions:

29 + 511963 = 511992
31 + 511961 = 511992
53 + 511939 = 511992
59 + 511933 = 511992
83 + 511909 = 511992
101 + 511891 = 511992
149 + 511843 = 511992
181 + 511811 = 511992

Showing the first eight; more decompositions exist.
