Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515156, here are decompositions:

3 + 515153 = 515156
7 + 515149 = 515156
13 + 515143 = 515156
67 + 515089 = 515156
223 + 514933 = 515156
283 + 514873 = 515156
337 + 514819 = 515156
373 + 514783 = 515156

Showing the first eight; more decompositions exist.
