Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511924, here are decompositions:

113 + 511811 = 511924
131 + 511793 = 511924
137 + 511787 = 511924
167 + 511757 = 511924
233 + 511691 = 511924
293 + 511631 = 511924
383 + 511541 = 511924
401 + 511523 = 511924

Showing the first eight; more decompositions exist.
