Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512140, here are decompositions:

3 + 512137 = 512140
47 + 512093 = 512140
131 + 512009 = 512140
149 + 511991 = 512140
179 + 511961 = 512140
281 + 511859 = 512140
347 + 511793 = 512140
353 + 511787 = 512140

Showing the first eight; more decompositions exist.
