Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505748, here are decompositions:

37 + 505711 = 505748
79 + 505669 = 505748
109 + 505639 = 505748
211 + 505537 = 505748
337 + 505411 = 505748
349 + 505399 = 505748
379 + 505369 = 505748
409 + 505339 = 505748

Showing the first eight; more decompositions exist.
