Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511172, here are decompositions:

3 + 511169 = 511172
19 + 511153 = 511172
61 + 511111 = 511172
139 + 511033 = 511172
229 + 510943 = 511172
241 + 510931 = 511172
283 + 510889 = 511172
349 + 510823 = 511172

Showing the first eight; more decompositions exist.
