Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528042, here are decompositions:

29 + 528013 = 528042
41 + 528001 = 528042
59 + 527983 = 528042
61 + 527981 = 528042
101 + 527941 = 528042
113 + 527929 = 528042
173 + 527869 = 528042
191 + 527851 = 528042

Showing the first eight; more decompositions exist.
