Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529140, here are decompositions:

11 + 529129 = 529140
13 + 529127 = 529140
19 + 529121 = 529140
23 + 529117 = 529140
37 + 529103 = 529140
43 + 529097 = 529140
89 + 529051 = 529140
97 + 529043 = 529140

Showing the first eight; more decompositions exist.
