Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83874, here are decompositions:

5 + 83869 = 83874
17 + 83857 = 83874
31 + 83843 = 83874
41 + 83833 = 83874
61 + 83813 = 83874
83 + 83791 = 83874
97 + 83777 = 83874
101 + 83773 = 83874

Showing the first eight; more decompositions exist.
