Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503998, here are decompositions:

29 + 503969 = 503998
59 + 503939 = 503998
71 + 503927 = 503998
179 + 503819 = 503998
227 + 503771 = 503998
281 + 503717 = 503998
389 + 503609 = 503998
449 + 503549 = 503998

Showing the first eight; more decompositions exist.
