Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512130, here are decompositions:

29 + 512101 = 512130
37 + 512093 = 512130
71 + 512059 = 512130
83 + 512047 = 512130
109 + 512021 = 512130
139 + 511991 = 512130
167 + 511963 = 512130
191 + 511939 = 512130

Showing the first eight; more decompositions exist.
