Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511178, here are decompositions:

7 + 511171 = 511178
67 + 511111 = 511178
139 + 511039 = 511178
271 + 510907 = 511178
331 + 510847 = 511178
487 + 510691 = 511178
727 + 510451 = 511178
859 + 510319 = 511178

Showing the first eight; more decompositions exist.
