Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511138, here are decompositions:

29 + 511109 = 511138
137 + 511001 = 511138
149 + 510989 = 511138
197 + 510941 = 511138
311 + 510827 = 511138
431 + 510707 = 511138
461 + 510677 = 511138
521 + 510617 = 511138

Showing the first eight; more decompositions exist.
