Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511394, here are decompositions:

3 + 511391 = 511394
7 + 511387 = 511394
43 + 511351 = 511394
61 + 511333 = 511394
67 + 511327 = 511394
97 + 511297 = 511394
151 + 511243 = 511394
157 + 511237 = 511394

Showing the first eight; more decompositions exist.
