Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503440, here are decompositions:

17 + 503423 = 503440
59 + 503381 = 503440
71 + 503369 = 503440
89 + 503351 = 503440
101 + 503339 = 503440
137 + 503303 = 503440
173 + 503267 = 503440
191 + 503249 = 503440

Showing the first eight; more decompositions exist.
