Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511972, here are decompositions:

11 + 511961 = 511972
113 + 511859 = 511972
179 + 511793 = 511972
269 + 511703 = 511972
281 + 511691 = 511972
389 + 511583 = 511972
431 + 511541 = 511972
449 + 511523 = 511972

Showing the first eight; more decompositions exist.
