Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511144, here are decompositions:

83 + 511061 = 511144
131 + 511013 = 511144
317 + 510827 = 511144
461 + 510683 = 511144
467 + 510677 = 511144
563 + 510581 = 511144
593 + 510551 = 511144
743 + 510401 = 511144

Showing the first eight; more decompositions exist.
