Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174842, here are decompositions:

13 + 174829 = 174842
43 + 174799 = 174842
79 + 174763 = 174842
139 + 174703 = 174842
163 + 174679 = 174842
193 + 174649 = 174842
211 + 174631 = 174842
229 + 174613 = 174842

Showing the first eight; more decompositions exist.
