Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511906, here are decompositions:

47 + 511859 = 511906
113 + 511793 = 511906
149 + 511757 = 511906
347 + 511559 = 511906
383 + 511523 = 511906
419 + 511487 = 511906
443 + 511463 = 511906
449 + 511457 = 511906

Showing the first eight; more decompositions exist.
