Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939842, here are decompositions:

3 + 939839 = 939842
19 + 939823 = 939842
73 + 939769 = 939842
103 + 939739 = 939842
181 + 939661 = 939842
193 + 939649 = 939842
229 + 939613 = 939842
331 + 939511 = 939842

Showing the first eight; more decompositions exist.
