Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517802, here are decompositions:

73 + 517729 = 517802
163 + 517639 = 517802
193 + 517609 = 517802
199 + 517603 = 517802
331 + 517471 = 517802
409 + 517393 = 517802
421 + 517381 = 517802
499 + 517303 = 517802

Showing the first eight; more decompositions exist.
