Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511274, here are decompositions:

13 + 511261 = 511274
31 + 511243 = 511274
37 + 511237 = 511274
61 + 511213 = 511274
73 + 511201 = 511274
97 + 511177 = 511274
103 + 511171 = 511274
151 + 511123 = 511274

Showing the first eight; more decompositions exist.
