Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525042, here are decompositions:

13 + 525029 = 525042
29 + 525013 = 525042
41 + 525001 = 525042
43 + 524999 = 525042
59 + 524983 = 525042
61 + 524981 = 525042
71 + 524971 = 525042
73 + 524969 = 525042

Showing the first eight; more decompositions exist.
