Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528742, here are decompositions:

23 + 528719 = 528742
83 + 528659 = 528742
113 + 528629 = 528742
131 + 528611 = 528742
233 + 528509 = 528742
251 + 528491 = 528742
359 + 528383 = 528742
443 + 528299 = 528742

Showing the first eight; more decompositions exist.
