Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945842, here are decompositions:

19 + 945823 = 945842
31 + 945811 = 945842
43 + 945799 = 945842
103 + 945739 = 945842
109 + 945733 = 945842
211 + 945631 = 945842
241 + 945601 = 945842
379 + 945463 = 945842

Showing the first eight; more decompositions exist.
