Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529842, here are decompositions:

13 + 529829 = 529842
23 + 529819 = 529842
29 + 529813 = 529842
31 + 529811 = 529842
101 + 529741 = 529842
149 + 529693 = 529842
151 + 529691 = 529842
193 + 529649 = 529842

Showing the first eight; more decompositions exist.
