Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520042, here are decompositions:

11 + 520031 = 520042
23 + 520019 = 520042
53 + 519989 = 520042
71 + 519971 = 520042
179 + 519863 = 520042
239 + 519803 = 520042
359 + 519683 = 520042
431 + 519611 = 520042

Showing the first eight; more decompositions exist.
