Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469842, here are decompositions:

19 + 469823 = 469842
31 + 469811 = 469842
41 + 469801 = 469842
73 + 469769 = 469842
89 + 469753 = 469842
151 + 469691 = 469842
193 + 469649 = 469842
211 + 469631 = 469842

Showing the first eight; more decompositions exist.
