Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511960, here are decompositions:

101 + 511859 = 511960
149 + 511811 = 511960
167 + 511793 = 511960
173 + 511787 = 511960
257 + 511703 = 511960
269 + 511691 = 511960
401 + 511559 = 511960
419 + 511541 = 511960

Showing the first eight; more decompositions exist.
