Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503280, here are decompositions:

13 + 503267 = 503280
31 + 503249 = 503280
47 + 503233 = 503280
53 + 503227 = 503280
67 + 503213 = 503280
73 + 503207 = 503280
83 + 503197 = 503280
149 + 503131 = 503280

Showing the first eight; more decompositions exist.
