Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511226, here are decompositions:

3 + 511223 = 511226
13 + 511213 = 511226
73 + 511153 = 511226
103 + 511123 = 511226
139 + 511087 = 511226
193 + 511033 = 511226
283 + 510943 = 511226
307 + 510919 = 511226

Showing the first eight; more decompositions exist.
