Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529742, here are decompositions:

19 + 529723 = 529742
61 + 529681 = 529742
139 + 529603 = 529742
163 + 529579 = 529742
211 + 529531 = 529742
223 + 529519 = 529742
229 + 529513 = 529742
271 + 529471 = 529742

Showing the first eight; more decompositions exist.
