Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31842, here are decompositions:

43 + 31799 = 31842
71 + 31771 = 31842
73 + 31769 = 31842
101 + 31741 = 31842
113 + 31729 = 31842
179 + 31663 = 31842
193 + 31649 = 31842
199 + 31643 = 31842

Showing the first eight; more decompositions exist.
