Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505624, here are decompositions:

5 + 505619 = 505624
11 + 505613 = 505624
17 + 505607 = 505624
23 + 505601 = 505624
101 + 505523 = 505624
113 + 505511 = 505624
131 + 505493 = 505624
257 + 505367 = 505624

Showing the first eight; more decompositions exist.
