Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505654, here are decompositions:

11 + 505643 = 505654
41 + 505613 = 505654
47 + 505607 = 505654
53 + 505601 = 505654
131 + 505523 = 505654
173 + 505481 = 505654
353 + 505301 = 505654
467 + 505187 = 505654

Showing the first eight; more decompositions exist.
