Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511244, here are decompositions:

7 + 511237 = 511244
31 + 511213 = 511244
43 + 511201 = 511244
67 + 511177 = 511244
73 + 511171 = 511244
157 + 511087 = 511244
211 + 511033 = 511244
313 + 510931 = 511244

Showing the first eight; more decompositions exist.
