Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529642, here are decompositions:

5 + 529637 = 529642
23 + 529619 = 529642
293 + 529349 = 529642
383 + 529259 = 529642
401 + 529241 = 529642
461 + 529181 = 529642
521 + 529121 = 529642
593 + 529049 = 529642

Showing the first eight; more decompositions exist.
