Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505744, here are decompositions:

17 + 505727 = 505744
53 + 505691 = 505744
101 + 505643 = 505744
131 + 505613 = 505744
137 + 505607 = 505744
233 + 505511 = 505744
251 + 505493 = 505744
263 + 505481 = 505744

Showing the first eight; more decompositions exist.
