Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511126, here are decompositions:

3 + 511123 = 511126
17 + 511109 = 511126
107 + 511019 = 511126
113 + 511013 = 511126
137 + 510989 = 511126
353 + 510773 = 511126
359 + 510767 = 511126
419 + 510707 = 511126

Showing the first eight; more decompositions exist.
