Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505544, here are decompositions:

7 + 505537 = 505544
31 + 505513 = 505544
43 + 505501 = 505544
97 + 505447 = 505544
223 + 505321 = 505544
307 + 505237 = 505544
313 + 505231 = 505544
331 + 505213 = 505544

Showing the first eight; more decompositions exist.
