Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513042, here are decompositions:

11 + 513031 = 513042
29 + 513013 = 513042
41 + 513001 = 513042
43 + 512999 = 513042
53 + 512989 = 513042
83 + 512959 = 513042
113 + 512929 = 513042
139 + 512903 = 513042

Showing the first eight; more decompositions exist.
