Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503398, here are decompositions:

17 + 503381 = 503398
29 + 503369 = 503398
47 + 503351 = 503398
59 + 503339 = 503398
101 + 503297 = 503398
131 + 503267 = 503398
149 + 503249 = 503398
167 + 503231 = 503398

Showing the first eight; more decompositions exist.
